This is one of the most asked JavaScript Interview Questions, it was asked to me by FlexCar company. Similarly, many other companies asked to create a polyfill for map, reduce, Promise.all, Promise.race and many others.

In this tutorial, we'll dive into the world of polyfills and learn how to create a custom polyfill for the JavaScript filter method. The filter method is a powerful tool for manipulating arrays in JavaScript, allowing you to create new arrays containing elements that meet certain criteria. However, it may not be supported in all environments, leading to compatibility issues in older browsers.
To address this challenge, we'll walk through the process of creating a polyfill-a piece of code that replicates the functionality of a missing feature. By extending the Array.prototype object with our own implementation of the filter method, we can ensure cross-browser compatibility and leverage the power of modern JavaScript features in our applications.
If you are preparing for an interview then this is the prefect channel for you to follow. We will post the most asked questions. Join us on this coding journey, and let's elevate our skills together.
