Show HN: Omg-Curry – JavaScript currying library

I like this too (and use a version myself) however this form only supports one argument at a time. E.g. add(1,2) is going to return the curry of add(1), which is not what you want. The OP's function doesn't have that problem.

Something I would really like, although this would require some language-level changes, I think, is the ability to curry arguments in any order, maybe using placeholders. So you could say add(_, 2) and get back a function of one argument, such that if you call it with 1, for example, you invoke add(1, 2).

What it ends up being for normal usage is something like this:

  add(1)(2)

Which is admittedly a little bit clunky, though from a quick read I don't think the library helps with this.

You might be interested in the "pipeline operator" proposal. In addition to pairing nicely with curried functions, it offers a certain amount of re-ordering.

Yeah I think your quick read is off:

  add4(1)(3)(5)(10)
  add4(1)(3,5)(10)
  add4(1,3,5,10)
  // 19
