Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during compilation.
Variable and function declarations are hoisted to the top of their scope.
Only declarations are hoisted, not initializations.
Function declarations take precedence over variable declarations.
Closures are functions that have access to their own scope, as well as the scope in which they were defined.
Closures allow functions to access variables from their outer scope even after the outer function has finished executing.
They are commonly used in event handlers, callbacks, and in functional programming.
Example: const outerFunction = () => { const outerVar = 'I am outer'; return () => { console.log(outerVar); };...
JavaScript is a high-level, interpreted programming language used for creating interactive websites and web applications.
JavaScript is often used for client-side scripting to make web pages interactive.
It can also be used for server-side development with Node.js.
JavaScript is versatile and can be used for creating games, mobile apps, and more.
Spread operator allows an iterable to be expanded in places where zero or more arguments or elements are expected. Rest operator collects all the remaining elements into an array.
Spread operator is denoted by three dots (...) and is used to expand elements of an iterable like an array or object.
Rest operator is also denoted by three dots (...) and is used to collect multiple elements into a single array.
Spread operator...
Callback hell is a situation in asynchronous JavaScript programming where multiple nested callbacks make the code difficult to read and maintain.
Occurs when multiple asynchronous operations are nested within each other
Leads to deeply nested code structure which is hard to read and debug
Can be avoided by using promises, async/await, or modularizing code
Asynchronous nature in Node JS refers to the ability of the program to execute multiple tasks simultaneously without blocking the main thread.
Allows non-blocking I/O operations, improving performance and scalability
Uses event-driven architecture to handle multiple requests concurrently
Uses callbacks, promises, and async/await for handling asynchronous operations
Async await in Node.js is a feature that allows you to write asynchronous code in a synchronous manner.
Async await is built on top of Promises in Node.js.
It allows you to write asynchronous code that looks like synchronous code, making it easier to read and maintain.
The 'async' keyword is used to define a function as asynchronous, while the 'await' keyword is used to wait for a Promise to resolve before continuing.

The questions ranged from prime number concepts to one question on linked list.
You are given two integers DAY_HOURS
and PARTS
. Consider a day with DAY_HOURS
hours, which can be divided into PARTS
equal parts. Your task is to determine the total ins...
Given DAY_HOURS and PARTS, find total instances of equivalent prime groups in a day divided into equal parts.
Divide the day into equal parts and check for prime groups at the same position in different parts.
Each prime group consists of prime numbers occurring at the same position in different parts.
Return the total number of equivalent prime groups found.
Ensure DAY_HOURS is divisible by PARTS and each hour in a prime
Given two linked lists representing two non-negative integers, where the digits are stored in reverse order (i.e., starting from the least significant digit to ...
Add two numbers represented as linked lists in reverse order and return the sum as a linked list.
Traverse both linked lists simultaneously, adding corresponding digits and carrying over if necessary.
Handle cases where one list is longer than the other by considering carry over.
Create a new linked list to store the sum digits in reverse order.
Return the head of the new linked list as the result.
Tip 1 : Do practice aptitude faithfully because it will help you in cracking the first round.
Tip 2 : Study concepts from different sites like Coding Ninjas, Geeks for Geeks for better understanding.
