The callback now receives an accumulator (it accumulates all the return values. Its value is the accumulation of a previously returned accumulations), a current value, a current index, and finally, the whole array.
**_map, filter and reduce _**are essentially just some of the most well-known, easy to use, higher-order functions that run provided callback on each element of an array.
In this article, we will explore how using map(), filter(), and reduce() can help make our code:
**1.**Easy to comprehend.
2. Less prone to side effects as these function don’t modify the actual array, and instead create a new one.
**3. **Avoid explicit loops.
Let’s explore and familiarize ourselves with these functions.
We all know Arrayscollection of variables, and we all have used to perform some operations like Creating an array, Removing an Item from an Array, Sorting the data of an Array and other manipulations.
In Functional Programming, we are using functions like foreach, map, filter, reduce, concatAll and other Higher Order Functions. So today I am describing these functions in deep and show you how you can use it in various scenarios.
