applyPipe is added now: https://github.com/MathisBullinger/froebel#applypipe It's included in version 0.21.0

It's just an identifier like any other defined in types.ts: https://github.com/MathisBullinger/froebel/blob/main/types.t... It's defined as type λ<TA extends any[] = any[], TR = any>

Thanks! Yes, it should work with any number of arguments. Or at least in theory it does, it seems that around 47 chained functions TypeScript will give up and stops computing the type. It's written in TypeScript v4.7.2 but I didn'

There isn't necessarily any issue with it besides maybe not being very maintainable. I just tried to find a generic solution for the fun of it

Looks like they define pipe separately for every number of arguments: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/mast...

Chaining assignments and using non-ascii characters as variable names is definitely not the norm in most TypeScript projects I've seen and worked on. When I started this project it was just for my own personal use and kind of a creativ

Yes, every function except the first one needs to have exactly one argument. Others have also said that `pipe` is not an ideal name for the function. So perhaps renaming it to `compose` and have `pipe` be of the form `pipe(arg, funA, funB,

Thanks for linking the code, I meant to link to the pipe section of the README but obviously botched that and can't change it now :) I was really exited about the pipe proposal and actively followed the discussion like 4 years ago. But

That looks interesting, I hadn't heard of the project. Will definitely have a look at the library. But it defines its pipe function the same way RXJS does, separately for any number of arguments: function pipe<A>(a: A): A f

When programming in a functional style, quite of often I find myself wanting to rewrite nested function calls as a chain. Hopefully at some point the proposed pipe operator will make it into JavaScript and TypeScript but for now defining a

Any feedback you might have would be appreciated. The library contains a bunch of utilities that I reuse between projects and thought might be worth sharing. What makes this library different from other utility libraries like e.g. Lodash is

There definitely are valid use cases for a Map, and even more now that we have WeakMaps (e.g. associating data DOM nodes). Or mapping functions to values, e.g. something like this: const returnCache = new Map<() => any, any>()

If the problem is just that you want to use non-primitive keys, that's what Maps are for. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...
