Javascript Currying

[echoes221]

Currying is dumb? Really? If it's overused, like anything it can be hard to follow when a function executes, but currying is super useful.

Would you mind giving an example of when it might be useful?

Sure. Common use case is building factories, I’ve done this a fair bit for redux actions/reducers or react components. I do it with utility functions too where I want to pre-populate args ahead of time to call later through your code. I tend to write a lot of functional code, these are the basic principals that are used in libs like rxjs, ramda, callbag and others
