Map vs Filter vs Reduce in Javascript - NodeJS tutorial for beginners

Map in Javascript

It creates a new array with the results of calling a function for every array element

Filter in Javascript

What if you have an array, but only want some of the elements in it? That’s where .filter() comes in!

Reduce in Javascript

It reduces the array to a single value. The return value of the function is stored in an accumulator (result/total).
