FroLeMageBlanc··on Show HN: A JavaScript function that looks and behaves like a pipe operator

If you can’t understand the difference between pure (no side effects) and functional (applying and composing functions), I don’t know what to tell you.

Purely functional programming is a subset of functional programming (see F# for instance). I was referring to the pipe operator syntax common to many functional programming languages like Haskell, F#, OCaml, Elixir, Elm and so on...

Haha thanks! Yes haters gonna hate. If you like it, use it; if you don’t, simply don’t use it ;)

Is functional programming a joke? YMMV...

Thanks! I’m currently trying to find a better TS type but that’s a bit hairy...

The pipe function of `fp-ts` doesn’t have direct access to methods and properties of the pipe output like Verticalize. You have to wrap them into anonymous functions. Same with promises.

Author here. Thanks for your nice comment. I added a note to show the "normal" autoformatted syntax.

Author here. Thanks for your nice comment. I added a note to say it does work with autoformatters too. Actually someone in a comment below said he or she prefers the autoformatted syntax.
