Understanding the difference between Map and ForEach method

In the realm of JavaScript programming, optimizing your code is not just about functionality, but also about efficiency and readability. Two array methods, map and forEach, often come into play when you’re working with arrays. While they might seem similar at first glance, they serve distinct purposes and can greatly impact your coding approach. In this article, we’ll embark on a journey to unravel the distinctions between these methods, exploring their applications and the scenarios where they shine. So, let’s delve into the world of JavaScript arrays and elevate our coding prowess!

Understanding the Basics

Map Method: Transforming with Precision

The map method is a versatile tool in your JavaScript arsenal. It traverses each element of an array and applies a callback function to it. The beauty lies in its ability to create a new array based on the results of the callback function, leaving the original array untouched. This makes it ideal for scenarios where you need to transform data while maintaining a clear separation between the original and transformed arrays.
