The map method is a powerful tool in JavaScript arrays that allows developers to transform each element of an array with a provided callback function. While widely supported in modern JavaScript environments, older browsers may lack native support for this method. In this blog post, we’ll explore how to create a polyfill for the map […]

In JavaScript, object cloning is a common task, but deep copying an object while also handling circular references presents a unique challenge. Circular references occur when an object contains a reference to itself or to another object that eventually leads back to the original object. In this blog post, we’ll explore how to implement a […]

In JavaScript, object cloning is a common task, but deep cloning, which involves creating a complete and independent copy of an object and its nested properties, presents unique challenges. Here, we’ll explore the concept of deep cloning and learn how to implement it effectively in JavaScript. What is Deep Cloning? Deep cloning refers to the […]

You will be given a number, and need to prepare N X N boxes on the screen, clicking on it should show a blue colour. While Preparing we need to create a single box first then we need to build the N X N Box grid. This question was asked in Kotak‘s interview first round, […]

In the vast realm of JavaScript, arrays reign supreme as versatile containers of data. But when arrays nest within each other, navigating through their depths can be a daunting task. Fear not, fellow coder! In this blog post, we embark on a quest to conquer nested arrays using the mighty power of the `reduce` Array […]

Nested objects are a common data structure in JavaScript, providing a convenient way to organize and represent complex data. However, working with nested objects can sometimes be challenging, especially when you need to access specific properties or transform the data into a different format. In this post, we’ll explore how to flatten nested objects in […]

The interview was around 1 hour and the interviewer has almost 6 years of experience in frontend application development. Question 1: Create a polyfill for the Filter method (Link to the article) Question 2: Create a polyfill for Object.entries (Link to the article) Question 3: Create a custom hook that provides a counter that can […]

In modern JavaScript development, we often rely on array methods like filter to manipulate and extract data from arrays with ease. However, older browsers may lack support for these convenient methods, leading to compatibility issues in our projects. In this blog post, we’ll explore the concept of polyfills and walk through the process of creating […]
