If it works better than the previous one or covers more use-cases, PR it. I like what I see. 😉

Can you show an example of how that would work?
I believe this don't account for currying of variadic functions like Math.min for example.

@elderhsouza yes, you right, it was just an example, we have to define arity
const curry = (fn, arity = fn.length, ...args) =>
arity <= args.length
? fn(...args)
: curry.bind(null, fn, arity, ...args)
// curry(Math.pow)(2)(10) -> 1024
// curry(Math.min, 3)(10)(50)(2) -> 2

@elderhsouza the curry may not work
const curry = (f, arity = f.length, next) =>
(next = prevArgs =>
nextArg => {
const args = [ ...prevArgs, nextArg ];
return args.length >= arity ? f(...args) : next(args);
}
)([]);
// curry(Math.min, 3)(10, 200)(2) -> not work
I think should like this
const curry = (f, arity = f.length, next) =>
(next = prevArgs =>
(...nextArg) => {
const args = [ ...prevArgs, ...nextArg ];
return args.length >= arity ? f(...args) : next(args);
}
)([]);

@broadsw0rd I like this one, haven't used currying like this one yet, but I can see how it can be useful, solid implementation.
@linrui1994 That's really elegant and terse, I tested all versions with the same use cases and it seems to work for all of it.
@Chalarangelo Great discussion here, wanna jump in?
