Function composition in Javascript

Function composition is cool. Little bit tricky, but, whatever, right? Anyways, we start out with an easy example and then move onto something a bit more challenging. Don't hate comment me, bro! #javascript #coding #algorithms

Good job. Good example. For unknow number of functions you can make a helper function like this:
function main(...fns)
{return fns.reduce(compose)}

I get lost in the part of the "for of loop" where on the right side he uses an or operator ||, How this is evaluated? Thanks in advance. If anyone could suggest what I need to focus on, in order to learn about it, I will really appreciate it.

Most of tutorial show composition along with bad practices in js. Your code is not beautiful but does show composition in good way. Good job.
