![]() Let's take the same users array we used in the filter method. But here, I will share a real-life scenario I faced that directs me to use Reduce. The examples on the internet for Reduce are so simple that we can't relate them to a real-life problem. The new array will have the same length as the current.Īrrays.map((element, index, array) =>, initialValue)Īfter taking an example, you will get it clear. So you can't skip the element if you want. Unlike a filter, a map does not discard any element instead it manipulates the value of elements. In each iteration, it applies a callback function on the current array element and finally returns a completely new array. The map method is used to iterate over an array. That's what you need to know about the filter method. ![]() Based on this return value, the element is added or discarded into the new array. ![]() You may have noticed that the callback function returns the boolean value true or false.
