How has Haskell influenced your JS coding?

Great question!

The single biggest influence Haskell had on my JavaScript is that I don't write much of it anymore. And that's no coincidence. There are so many things in Haskell I enjoy that either don't exist in JavaScript at all or are just painfully hard to replicate. I simply don't have much fun bending JavaScript to my needs anymore.

That said, when I still write JavaScript it does in fact look very different from what it did a couple of years ago.

• I push side effects to the boundaries of the system.
• I embrace immutability wherever possible. This means simple things like not using var or let at all, using proper immutable data structures instead of the builtins and use abstractions on top of unavoidably mutable rubbish like the DOM.
• I use transpilers. I didn't want to use this as a top-level answer, because it feels a bit cheap. PureScript, Elm and GHCJS (of which I've only used the first two in anger) are fantastic pieces of software and if I the constraints a certain project exists in, I would always pick one of those over plain Vanilla JS.
• My code is a series of transformations, not a bunch of disseminated mutations. Even without monads in JavaScript, you can express effects as a series of computations against an initial state.

Cool answer @passy!

@arthurvr Thanks! :)

Almost got there without "monads" :-P

Hah, as if I'd miss an opportunity for that. :D
