What tasks can you recommend for practicing functional programming skills and array processing in JavaScript?

Question

JavaScript

Good afternoon,
I have a lot of programmers in my team who not only have not heard about functional programming, but also do not know about working with arrays using map, reduce, filter, find ...
I'm trying to raise their level a little :) and I want to ask send interesting tasks that can be set to practice the skill of processing arrays in a functional style.
Thanks in advance.

Answer 1

NP
Select JS and tag arrays+functionality

Answer 2

I would advise you to read a series of articles on functional programming (4 parts):

Further practice - any tasks related to arrays. For example, you can take codewars and perform various katas, only agree on the mandatory use of functional style. You can also consider options for refactoring existing code (parts of code) to a functional style.
