If you are looking to start a career in web development, JavaScript is an essential skill. The demand for JavaScript developers is robust; the U.S. Bureau of Labor Statistics projects an 8% growth in employment for web developers and digital designers from 2023 to 2033, faster than the average for all occupations. This highlights the importance of being well-prepared for technical interviews that assess both theoretical knowledge and practical skills in JavaScript.​

This article provides a list of the top JavaScript interview questions for freshers that will help you prepare for your next job interview. 

An Introduction to JavaScript

JavaScript is a high-level, dynamic, and interpreted programming language that enables developers to create interactive and dynamic websites. It is one of the three core technologies of web development alongside HTML and CSS. JavaScript was originally developed by Netscape as a client-side scripting language, but today it has evolved into a full-stack language with the introduction of Node.js for server-side development.

JavaScript enables web pages to respond to user interactions in real time without reloading the entire page. This makes it the cornerstone of modern web applications, including single-page applications (SPAs) that provide a fluid user experience. With the advent of powerful frameworks like React, Angular, and Vue, JavaScript continues to grow in importance in the world of web development.

In addition to front-end development, JavaScript is increasingly used in back-end development, mobile app development (with tools like React Native), and desktop application development. Understanding the fundamentals of JavaScript is essential for anyone pursuing a career in software development.

Now, let's look into some basic JavaScript interview questions, essential for getting started in any developer role.

Basic JavaScript Interview Questions for Freshers

Understanding the basic functionalities and features of JavaScript is crucial for entry-level positions and those new to web development. These questions typically focus on fundamental concepts like data types, variables, functions, and control flow, forming the foundation of your JavaScript knowledge.

1. What is JavaScript?

Why interviewers ask this question: Interviewers ask this question to assess whether you have a fundamental understanding of JavaScript and its purpose in web development. It’s essential to know what JavaScript is and why it’s used.

Sample Answer

JavaScript is a dynamic, high-level programming language used to create interactive effects within web browsers. It is an essential tool for front-end web development and allows developers to implement complex features like animations, form validation, and interactive maps. JavaScript runs in the browser, which makes web pages dynamic without the need to refresh the page. In addition to front-end development, JavaScript can also be used for back-end development with Node.js, enabling full-stack development.

2. What are variables in JavaScript?

Why interviewers ask this question: Variables are one of the most basic building blocks in programming. This question evaluates your understanding of how JavaScript handles data storage and variable assignment.

Sample Answer

In JavaScript, a variable is used to store data that can be referenced and manipulated throughout the program. Variables can be declared using three keywords: var, let, and const.

• var: The traditional way to declare a variable. However, it has function scope and is now considered outdated due to its inconsistent behaviour in block scoping.
• let: A modern keyword for declaring variables. It provides block-level scoping, making it more predictable and safer to use in large codebases.
• const: Used for variables that should not be reassigned after their initial declaration. Like let, it also has a block-level scope.

JavaScript allows dynamic typing, meaning variables can store any type of data—such as numbers, strings, objects, arrays, or even functions—and their type can change during runtime.

3. What are the different data types in JavaScript?

Why interviewers ask this question: Understanding JavaScript’s data types is fundamental for manipulating data and writing effective code. This question helps assess if you are familiar with JavaScript's type system.

Sample Answer

JavaScript has two categories of data types: primitive types and reference types.

• Primitive Types:
  
  • String: Represents textual data like "Hello, world!".
  • Number: Represents numeric values, including integers and floating-point numbers, like 42 or 3.14.
  • Boolean: Represents a logical entity that can either be true or false.
  • Null: Represents an intentional absence of any value or object. It is often used to indicate the lack of a value or as a placeholder.
  • Undefined: Represents a variable that has been declared but has not yet been assigned a value.
  • Symbol: A unique and immutable value that can be used as the key of an object property, ensuring that the property key is unique.
• Reference Types:
  
  • Object: Represents a collection of key-value pairs. Objects can store more complex data structures.
  • Array: A special type of object used for storing ordered collections of data.
  • Function: In JavaScript, functions are first-class objects, meaning they can be assigned to variables, passed as arguments, or returned from other functions.

Primitive types are immutable and compared by value, while reference types are compared by reference, meaning they point to the same memory location.

4. What is ‘this’ in JavaScript?

Why interviewers ask this question: The ‘this’ keyword in JavaScript can be tricky. Interviewers ask this question to test your understanding of the context in which it is used.

Sample Answer

In JavaScript, the ‘this’ keyword refers to the execution context of the function it is used in. Its value is determined by how a function is called, and it can refer to different objects depending on the situation:

• In a regular function, ‘this’ refers to the global object, which is a window in browsers and global in Node.js. This behaviour can be unexpected, especially when used inside a function that is not a method.
• In an object method, ‘this’ refers to the object that owns the method. For example, if a method is invoked on an object, ‘this’ refers to that object.
• Arrow functions behave differently with ‘this’. They do not have their own ‘this’ context. Instead, ‘this’ is lexically inherited from the outer function in which the arrow function is defined.

5. What is the difference between null and undefined?

Why interviewers ask this question: This is a common question because null and undefined are often confused despite their important differences. The interviewer is assessing whether you understand how these two types work in JavaScript.

Sample Answer

Both null and undefined represent the absence of a value, but they are used in different contexts:

• null is an intentional assignment of no value. It is explicitly used to indicate that a variable has no value or that an object property is intentionally empty. It is often used as a placeholder or to reset a variable.
• undefined is the default value assigned to variables that have been declared but not yet initialized. If you declare a variable without assigning a value, JavaScript automatically assigns it the value undefined. It is also the return value for functions that don’t explicitly return anything.

6. What are JavaScript functions, and how do they work?

Why interviewers ask this question: Functions are fundamental in JavaScript. This question is important to evaluate whether you understand the concept of functions and how they help organize code.

Sample Answer

A function in JavaScript is a block of reusable code designed to perform a particular task. Functions can accept parameters and return values. They allow for better modularity and reusability of code. Functions are defined using the function keyword, followed by a name, a set of parentheses for parameters, and a block of code. Functions can also be anonymous, in which case they do not have a name but can still be invoked.

7. What is the event loop in JavaScript?

Why interviewers ask this question: The event loop is crucial for understanding asynchronous programming in JavaScript. This question helps interviewers gauge your understanding of how JavaScript handles concurrency and non-blocking operations.

Sample Answer

JavaScript operates in a single-threaded manner, meaning it can only perform one operation at a time. However, with asynchronous programming, JavaScript can handle tasks like I/O operations or timers without blocking the execution of other code. The event loop is responsible for executing the queued-up tasks after the current operation is completed. When a task (like a callback or promise) is executed, it is added to the event queue and eventually processed by the event loop once the main execution stack is empty.

Once you’re comfortable with the basics, it’s time to move on to intermediate JavaScript interview questions for freshers, which will further test your problem-solving skills and deeper understanding of JavaScript.

Intermediate JavaScript Interview Questions for Freshers

Intermediate JavaScript questions focus on more advanced concepts and problem-solving techniques beyond the basics. These questions typically explore topics like closures, callbacks, promises, and asynchronous programming, testing your deeper understanding of JavaScript.

1. What is closure in JavaScript?

Why interviewers ask this question: Closures are a powerful feature in JavaScript, allowing functions to access variables from an outer scope. This question checks if you understand this concept and its uses.

Sample Answer

A closure occurs when a function is defined inside another function, and it "remembers" the variables from its outer function even after the outer function has finished executing. This allows the inner function to access and manipulate variables that were in scope when it was created, even if those variables are no longer available in the outer function's scope. Closures are used extensively for tasks like data encapsulation and creating private variables.

2. What is event delegation in JavaScript?

Why interviewers ask this question: Event delegation is an important concept for handling events efficiently, especially in dynamic applications. The interviewer may ask this to test your understanding of event handling in JavaScript.

Sample Answer

Event delegation is a technique in JavaScript where a single event listener is added to a parent element instead of attaching individual event listeners to each child element. This takes advantage of event bubbling, where an event triggered on a child element bubbles up to its parent element in the DOM hierarchy. By using event delegation, you can listen for events on parent elements and handle events for all child elements, including those added dynamically.

3. What is the difference between == and === in JavaScript?

Why interviewers ask this question: This question tests your understanding of JavaScript's equality operators and whether you know the potential pitfalls of using loose equality.

Sample Answer

In JavaScript, == is the loose equality operator, which compares two values for equality but performs type coercion. For example, "5" == 5 would return true because JavaScript automatically converts the string "5" to the number 5. On the other hand, === is the strict equality operator, which compares both the value and the type of the operands. For example, "5" === 5 would return false because the operands are of different types (string and number). It is generally recommended to use === for comparisons to avoid unexpected results due to type coercion.

4. What are JavaScript modules?

Why interviewers ask this question: Modules help in organizing code and are essential for large-scale applications. This question checks your knowledge of modular programming and JavaScript’s approach to code reuse.

Sample Answer

JavaScript modules allow developers to split code into smaller, reusable pieces, which makes it easier to manage and maintain. JavaScript modules use import and export to share functions, variables, or objects between different files. The export keyword allows you to make variables, functions, or objects accessible outside the module, while import allows you to bring those exports into other files. Modules help with better code organization and prevent polluting the global namespace.

5. What is the difference between synchronous and asynchronous code in JavaScript?

Why interviewers ask this question: Synchronous and asynchronous programming are core concepts in JavaScript. Understanding them is crucial for managing tasks that don’t block the main thread.

Sample Answer

Synchronous code executes line by line, blocking the program’s execution until the current operation finishes. This can lead to delays, especially when handling tasks like API calls or file operations. Asynchronous code, on the other hand, allows other operations to continue while waiting for the task to complete, improving efficiency. Asynchronous code in JavaScript is typically managed using callbacks, promises, or async/await. This enables non-blocking behaviour, ensuring the application remains responsive.

6. What is a higher-order function in JavaScript?

Why interviewers ask this question: Higher-order functions are an advanced concept in JavaScript that allow functions to operate on other functions. This question assesses whether you are familiar with functional programming techniques.

Sample Answer

A higher-order function is a function that either takes one or more functions as arguments, returns a function, or both. Higher-order functions are often used to create reusable code or to abstract common functionality. Examples of higher-order functions in JavaScript include methods like map, filter, and reduce that operate on arrays. These functions can help make code more concise, reusable, and declarative.

7. What is event bubbling in JavaScript?

Why interviewers ask this question: Event bubbling is a fundamental concept in event handling in JavaScript. Interviewers ask this question to test your understanding of how events propagate in the DOM.

Sample Answer

Event bubbling is a type of event propagation in which an event that is triggered on a child element "bubbles up" to its parent elements. This happens in the DOM hierarchy, where the event starts from the target element and moves to the root. Event bubbling allows you to handle events on parent elements, making event delegation possible. You can prevent event bubbling using the stopPropagation() method if you want to stop the event from reaching parent elements.

8. What is a callback function in JavaScript?

Why interviewers ask this question: Callback functions are a common pattern in JavaScript for handling asynchronous operations. This question helps interviewers evaluate if you understand how to handle functions passed as arguments.

Sample Answer

A callback function is a function that is passed as an argument to another function and is executed after the completion of some task. It is commonly used in asynchronous operations like setTimeout, API calls, or event listeners. Using callbacks helps ensure that functions execute in the correct order, especially when dealing with time-consuming tasks. However, callback hell can occur when multiple nested callbacks are used, making the code harder to maintain.

9. What is the use of setTimeout() and setInterval() in JavaScript?

Why interviewers ask this question: These functions are fundamental for time-based operations in JavaScript. This question is important because it assesses your ability to manage delays and recurring tasks in asynchronous programming.

Sample Answer

• setTimeout() is used to execute a function once after a specified delay (in milliseconds). It allows you to delay the execution of a code block for a set period. For example, you might use setTimeout() to show a message after a few seconds or to delay an animation effect.
• setInterval(), on the other hand, repeatedly executes a function at a specified interval (in milliseconds). It’s useful for running periodic tasks, such as updating the time every second or polling for new data from a server. Both functions return a timer ID that can be used with clearTimeout() or clearInterval() to stop the execution if needed.

10. What is the use of bind() method in JavaScript?

Why interviewers ask this question: The bind() method is useful when you need to explicitly control the context in which a function is executed. This question tests your understanding of function execution and how this is managed.

 Sample Answer

The bind() method in JavaScript is used to set the value of ‘this’ for a given function. When called, bind() returns a new function that, when executed, has this set to the provided value. It is particularly useful when passing methods as callbacks, where the ‘this’ value might be lost or changed. It ensures that the function uses the correct context, especially in scenarios like event handling or async operations.

11. What is the difference between var, let, and const in JavaScript?

Why interviewers ask this question: This question checks your knowledge of variable declaration and scope, which are critical for writing clean and efficient JavaScript.

Sample Answer

• var: The var keyword is used to declare variables with function scope, meaning the variable is accessible within the function where it is declared or globally if declared outside of any function. It can be redeclared within its scope, which may lead to unintentional bugs.
• let: Introduced in ES6, let allows you to declare variables with block scope, meaning they are only accessible within the block (e.g., inside loops or conditionals) where they are declared. It cannot be redeclared in the same scope, which makes it more predictable than var.
• const: Similar to let, const is also block-scoped. However, variables declared with const cannot be reassigned after their initial value is set. This makes it ideal for defining constants or values that should not change during the program execution.

12. What are default parameters in JavaScript?

Why interviewers ask this question: This question tests your understanding of JavaScript’s function flexibility, especially when it comes to providing fallback values for function arguments.

Sample Answer

Default parameters in JavaScript allow you to assign default values to function parameters when no argument is passed during the function call. This ensures that the function still works as expected, even if some arguments are missing. It’s a useful feature for providing fallback values and improving the flexibility of your code.

For example, if a function expects a value but none is provided, the default parameter will automatically supply a pre-defined value. This saves the need for additional conditional checks inside the function and makes the code cleaner and more concise.

Default parameters also provide an easy way to handle cases where specific values are optional, allowing the function to behave in a predictable manner with or without certain arguments.

13. What is the typeof operator in JavaScript?

Why interviewers ask this question: The typeof operator is a fundamental part of JavaScript used to check data types. This question assesses your understanding of JavaScript’s type system.

Sample Answer

The typeof operator is used to check the type of a variable or value. It returns a string indicating the data type of the operand. This is particularly useful during runtime for debugging or validating data types. For example, typeof can return types such as "number", "string", "boolean", "undefined", "object", and "function".

It’s important to note that typeof null returns "object", which is a historical bug in JavaScript but has remained for backward compatibility. The typeof operator helps JavaScript developers ensure that variables are being used correctly according to their expected types, making type management easier in dynamic applications.

14. What is a JavaScript array?

Why interviewers ask this question: Arrays are a fundamental part of JavaScript. This question checks if you understand how arrays store collections of data.

Sample Answer

A JavaScript array is an ordered collection of values or items, which can be of any data type, such as numbers, strings, objects, or even other arrays. Arrays are zero-indexed, meaning the first item in an array has an index of 0, the second item has an index of 1, and so on.

Arrays are useful for storing multiple values under a single variable, enabling you to manage collections of related data more efficiently. JavaScript arrays are dynamic, meaning their size can change as elements are added or removed. They are also heterogeneous, meaning they can contain values of different types in the same array. For example, an array can have numbers, strings, and even objects as its elements.

15. What is a JavaScript object?

Why interviewers ask this question: Objects are key to organizing data in JavaScript. This question checks your understanding of how to structure data using objects.

Sample Answer

A JavaScript object is a collection of key-value pairs where each key is a string (or a symbol), and the corresponding value can be any data type, such as strings, numbers, arrays, or even other objects. Objects are a fundamental data structure in JavaScript used to represent real-world entities and store structured data.

Each key in an object is unique, and you can access the values associated with those keys using dot notation (object.key) or bracket notation (object['key']). Objects are highly versatile and are widely used for storing and manipulating data, especially in cases where the data has multiple properties or behaviours.

16. What is the difference between slice() and splice() in JavaScript?

Why interviewers ask this question: This question tests your knowledge of how to manipulate arrays in JavaScript.

Sample Answer

Both slice() and splice() are methods used to manipulate arrays, but they behave quite differently.

• slice(): This method returns a shallow copy of a portion of an array without modifying the original array. It takes two arguments: the start index and the end index. The array elements between the start and end indices are copied into a new array, leaving the original array unchanged. It is often used when you want to extract a section of an array.
• splice(): This method modifies the original array. It allows you to add, remove, or replace elements at a specific index. Unlike slice(), splice() directly alters the original array and does not return a new array. You can use splice() to add or remove elements from any position in the array.

17. What is the use of localStorage and sessionStorage in JavaScript?

Why interviewers ask this question: This question assesses your understanding of client-side storage in JavaScript, which is often used in web applications for saving user data.

Sample Answer

Why interviewers ask this question: localStorage and sessionStorage are both web storage APIs that allow data to be stored on the client's browser, but they differ in their persistence.

• localStorage: Data stored in localStorage is persistent and does not expire when the browser is closed. It allows you to store data in key-value pairs, and it persists even after the page is reloaded or the browser is closed. This makes it suitable for storing data that needs to be accessible across sessions, such as user preferences or authentication tokens.
• sessionStorage: Data stored in sessionStorage is only available for the duration of the page session. It is cleared when the browser window is closed. Like localStorage, it stores data in key-value pairs but is intended for data that should only persist while the user is on a particular page or within a single session.

18. What are arrow functions in JavaScript?

Why interviewers ask this question: This question assesses your knowledge of the syntax and how arrow functions work compared to traditional functions.

Sample Answer

Arrow functions provide a concise syntax for writing functions in JavaScript. They were introduced in ES6 and differ from regular functions in both syntax and behaviour. The main differences are:

• Syntax: Arrow functions have a shorter syntax than traditional function expressions. Instead of using the function keyword, arrow functions use =>, making them more compact and easier to write.
• Lexical this binding: One of the key differences is how arrow functions handle the ‘this’ keyword. In regular functions, the value of ‘this’ depends on how the function is called, whereas in arrow functions, ‘this’ is lexically bound. This means ‘this’ takes its value from the surrounding (enclosing) context, which is particularly useful in situations like callbacks or event handlers where the function is not called directly in the context of the object it operates on.

19. What is a promise in JavaScript?

Why interviewers ask this question: Promises are crucial for handling asynchronous operations in JavaScript. This question tests your understanding of promises and their role in managing asynchronous behavior.

Sample Answer

A promise in JavaScript is an object that represents the eventual completion or failure of an asynchronous operation and its resulting value. A promise can be in one of three states:

• Pending: The initial state, meaning the asynchronous operation is still in progress.
• Fulfilled: The state when the operation completes successfully, and a result is returned.
• Rejected: The state when the operation fails, and an error is returned.

After mastering intermediate concepts, you’ll be ready for the more intricate advanced JavaScript interview questions for freshers, which tackle complex topics and require a higher level of expertise.

Advanced JavaScript Interview Questions for Freshers

Advanced JavaScript questions explore more complex JavaScript concepts and problem-solving techniques. These questions often cover topics like closures, promises, asynchronous programming, and performance optimization, testing your ability to handle intricate coding challenges.

1. What is async/await in JavaScript?

Why interviewers ask this question: async/await is used for handling asynchronous code in a more readable way. This question tests whether you are familiar with modern JavaScript syntax for handling asynchronous operations.

Sample Answer

async/await is a syntactic feature that simplifies working with asynchronous code. async makes a function return a promise, and await is used inside the async function to pause execution until the promise resolves. This allows asynchronous code to be written in a synchronous style, improving readability. await can only be used within an async function, and it makes JavaScript wait until the promise resolves or rejects, streamlining asynchronous flow and error handling.

2. What is useEffect in React?

Why interviewers ask this question: Since React is widely used with JavaScript, this question checks if you understand the useEffect hook, which manages side effects in functional components.

Sample Answer

useEffect is a hook used in React to handle side effects in functional components. It is called after the component renders and is often used to fetch data, update the DOM, or subscribe to events. You can specify dependencies for useEffect, and it will only run when those dependencies change. It can also clean up after itself, such as removing event listeners or cancelling network requests when the component unmounts. This makes it a crucial tool for managing side effects in React applications.

3. What is the difference between synchronous and asynchronous execution in JavaScript?

Why interviewers ask this question: Synchronous and asynchronous programming are core concepts in JavaScript. Interviewers ask this to assess whether you understand how JavaScript handles tasks that take time, like reading files or making network requests.

Sample Answer

Synchronous execution occurs when each operation is completed, in sequence, one after another. It blocks the execution of further code until the current task finishes. Asynchronous execution, on the other hand, allows tasks to run in the background without blocking the rest of the program. JavaScript uses asynchronous programming to handle long-running tasks, such as I/O operations or network requests, ensuring that the main thread remains free for other operations, thus improving performance.

4. What is the difference between call(), apply(), and bind() in JavaScript?

Why interviewers ask this question: These methods are used to control the value of ‘this’ in JavaScript functions. This question tests your understanding of function invocation and the binding of context.

Sample Answer

• call(): Invokes a function with a specified ‘this’ value and arguments provided individually.
• apply(): Similar to call(), but arguments are passed as an array or array-like object.
• bind(): Returns a new function, where ‘this’ is permanently set to the specified value and initial arguments can be passed. Unlike call() and apply(), bind() doesn’t invoke the function immediately but creates a new bound function.

5. What is the useState hook in React?

Why interviewers ask this question: Since React is a common JavaScript library, this question tests your knowledge of React’s hooks and how state management works in functional components.

Sample Answer

The useState hook in React allows functional components to have a state. It returns an array with two elements: the current state value and a function to update that state. The useState hook is essential for managing and modifying data within a component, enabling the UI to react to state changes without requiring a class component. This hook makes it easy to track user input, handle dynamic data, and trigger re-renders of the component when state changes.
