Functional PHP VS Iter

A lot of this can be handled in userland. For examples libraries such as https://github.com/lstrojny/functional-php/blob/main/docs/functional-php.md handle a lot of this.

I’m also trying to use all of these at least once or twice to have these tools under my belt should I want them https://github.com/lstrojny/functional-php

The no-brainers to me are the missing array_some()/array_any() array_every()/array_all() and an array_search() that takes a predicate an iterable. I do these now in userland but an optimized native version would be nice.

Functional PHP, which provides a lot of similar functionality, also uses pluck and has for many years https://github.com/lstrojny/functional-php

While looking at functional-php, I saw a pretty neat way of doing composition with an array_reduce method, and wanted to recreate it in JavaScript. There are plenty of libraries that implement this (and do so more effectively), but it's pretty fun knowing that you can get this functionality with a couple lines of plain JavaScript.

I much prefer the https://github.com/nikic/iter approach for doing some collection magic, which is essentially based upon traversable and generator magic which doesn't create temporary in-memory data structures but works on item streams instead.

What about https://github.com/nikic/iter ?

Yes. We used it heavily when processing large amounts of data from huge API responses. I like how the whole processing chain can be built on top of it, for example using nikic/iter. Generators are also the heart of a low-memory JSON parsing library halaxa/json-machine, which I maintain, and many other similar projects.
