Here are 50 JavaScript Interview Questions and Answers for 2025:
What is JavaScript? JavaScript is a lightweight, interpreted programming language primarily used to create interactive and dynamic web pages. It's part of the core technologies of the web, along with HTML and CSS.
What are the data types in JavaScript? JavaScript has the following data types:
Primitive: String, Number, Boolean, Null, Undefined, Symbol, BigInt
Non-primitive: Object, Array, Function
What is the difference between null and undefined?
null is an assigned value representing no value.
undefined means a variable has been declared but not assigned a value.
Explain the concept of hoisting in JavaScript. Hoisting is JavaScript's default behavior of moving declarations to the top of the scope before code execution. var declarations are hoisted and initialized as undefined; let and const are hoisted but not initialized.
What is a closure in JavaScript? A closure is a function that retains access to its lexical scope, even when the function is executed outside of that scope.
What is the difference between “==” and “===” operators in JavaScript?
== checks for value equality (performs type coercion)
=== checks for value and type equality (strict equality)
Explain the concept of prototypal inheritance in JavaScript. Objects in JavaScript can inherit properties from other objects using the prototype chain. Every object has an internal link to another object called its prototype.
What are the different ways to define a function in JavaScript?
Function declaration: function greet() {}
Function expression: const greet = function() {}
Arrow function: const greet = () => {}
How does event delegation work in JavaScript? Event delegation uses event bubbling by attaching a single event listener to a parent element that handles events triggered by its children.
What is the purpose of the “this” keyword in JavaScript? this refers to the object that is executing the current function. Its value depends on how the function is called.
What are the different ways to create objects in JavaScript?
Object literals: const obj = {}
Constructor functions
Object.create()
Classes
Explain the concept of callback functions in JavaScript. A callback is a function passed as an argument to another function and executed after some operation is completed.
What is event bubbling and event capturing in JavaScript?
Bubbling: event goes from target to root.
Capturing: event goes from root to target. JavaScript uses bubbling by default.
What is the purpose of the “bind” method in JavaScript? The bind() method creates a new function with a specified this context and optional arguments.
Explain the concept of AJAX in JavaScript. AJAX (Asynchronous JavaScript and XML) allows web pages to be updated asynchronously by exchanging data with a server behind the scenes.
What is the “typeof” operator used for? The typeof operator returns a string indicating the type of a given operand.
How does JavaScript handle errors and exceptions? Using try...catch...finally blocks. Errors can also be thrown manually using throw.
Explain the concept of event-driven programming in JavaScript. Event-driven programming is a paradigm where the flow is determined by events such as user actions, sensor outputs, or messages.
What is the purpose of the “async” and “await” keywords in JavaScript? They simplify working with promises, allowing asynchronous code to be written like synchronous code.
What is the difference between a deep copy and a shallow copy in JavaScript?
Shallow copy copies top-level properties.
Deep copy duplicates all nested levels.
How does JavaScript handle memory management? JavaScript uses garbage collection to manage memory. It frees memory that is no longer referenced.
Explain the concept of event loop in JavaScript. The event loop handles asynchronous operations. It takes tasks from the queue and pushes them to the call stack when it is empty.

What is a promise in JavaScript? A promise is an object representing the eventual completion or failure of an asynchronous operation.
How do you handle errors in promises? Use .catch() or a try...catch block inside an async function.

const is block-scoped, cannot be re-declared or reassigned.
Explain the concept of event propagation in JavaScript. Event propagation includes capturing, target, and bubbling phases. JavaScript uses bubbling by default.
What are the different ways to manipulate the DOM in JavaScript?
getElementById(), querySelector(), createElement()
innerHTML, textContent, classList, setAttribute()
What is the purpose of “localStorage” and “sessionStorage”?
localStorage stores data with no expiration.

How do you handle asynchronous operations in JavaScript? Using callbacks, promises, or async/await syntax.
What is the purpose of the “forEach” method in JavaScript? forEach() executes a provided function once for each array element.
What are the differences between “let” and “var”?
let is block-scoped; var is function-scoped.
let cannot be accessed before declaration (Temporal Dead Zone).
Explain the concept of memoization in JavaScript. Memoization caches the results of function calls to avoid recalculating the same result.
What is the purpose of the “splice” method in JavaScript arrays? splice() adds/removes/replaces elements in an array in-place.
What is a generator function in JavaScript? A generator function (function*) can pause and resume execution using yield. It returns an iterator.
How does JavaScript handle variable scoping? Variables can be globally, function, or block scoped depending on how they are declared (var, let, const).
What is the purpose of the “split” method in JavaScript? split() splits a string into an array of substrings based on a specified separator.
What is the difference between a deep clone and a shallow clone of an object?
Shallow clone copies only references to nested objects.
Deep clone creates independent copies of all nested objects.
Explain the concept of the event delegation pattern. Event delegation attaches a single listener to a parent element to handle events from child elements via event bubbling.
What are the differences between JavaScript’s “null” and “undefined”?
null is intentional absence of value.
undefined means no value has been assigned.
What is the purpose of the “arguments” object in JavaScript? arguments is an array-like object accessible inside regular functions that contains the passed arguments.
What are the different ways to define methods in JavaScript objects?

What is the difference between “slice” and “splice” in JavaScript arrays?
slice() returns a shallow copy of part of an array.
splice() modifies the array by adding/removing elements.
What is the purpose of the “apply” and “call” methods in JavaScript? They invoke functions with a specific this context:
call() takes arguments individually.
apply() takes arguments as an array.
Explain the concept of the event loop in JavaScript and how it handles asynchronous operations. The event loop monitors the call stack and callback/task queues. It pushes callbacks to the stack when it’s clear, ensuring non-blocking async execution.
