Merge Sort is a classic sorting algorithm that uses the divide and conquer paradigm to efficiently sort an array, this is one of the most asked interview questions. Steps of Merge Sort Detailed Implementation in JavaScript Let’s implement Merge Sort step-by-step in JavaScript. Step 1: Splitting the Array First, we need a function to split […]

Sorting an array containing 0’s, 1’s, and 2’s is one of the most asked interview questions. In this article, we will explore the problem statement, discuss various approaches to solving it, and provide an optimised solution using the Dutch National Flag algorithm. Problem Statement Given an array of size n containing only the elements 0, […]

This “Minimum Number of Platforms Required for a Railway Station” is one of the most frequently asked DSA questions. I failed to crack two of the interviews due to this question. Problem Statement Given the arrival and departure times of trains at a railway station, determine the minimum number of platforms required so that no […]

The Valid Parenthesis Checker is a most asked question in the realm of Data Structures and Algorithms (DSA), it was asked to me personally in few of the interviews. Problem Statement Given a string containing just the characters “(“, “)”, “{“, “}”, “[“, and “]”, determine if the input string is valid. An input string […]

This is one of the most asked interview questions and In this interview article, we’ll dive deep into creating a robust Event Emitter in JavaScript, exploring its core functionalities and potential enhancements. This concept is also called as Publisher-Subscriber(Pub-Sub) Design pattern. Understanding the Event Emitter: An Event Emitter is a design pattern that allows different […]

In my recent job search, I have been interviewed at many companies, In one of the interviews, the Interviewer asked me to create a TicTacToe Game. The interviewer might expect you to solve this in React JS or React Native based on the role that you are being interviewed for. This question is even mentioned in […]

In my recent job search, I have been interviewed at many companies, In one of the interviews, the Interviewer asked me to create a TypeHead Component, where there will be an input box once the user types something in the input, it should give the suggestion key works based on the input. In modern applications, […]

The reduce method in JavaScript is an essential array method that helps in accumulating a single result from an array by applying a function to each element. It’s incredibly useful for tasks like summing up numbers, concatenating strings, or merging objects. In this interview article, we’ll explore how to create a polyfill for the reduce […]

Currying is a powerful technique in functional programming that transforms a function with multiple arguments into a series of functions that each take a single argument. This concept becomes particularly interesting when applied to objects with nested functions, enabling more flexible and reusable code. In this interview article, we’ll walk through how to create a […]

In modern web development, optimizing performance and reducing server load is crucial. One effective strategy is to cache API responses, so repeated requests for the same data can be served quickly without hitting the server multiple times. In this blog, we’ll walk through creating a functional API call cache in JavaScript. This is created using […]
