28Implement curry() supporting partial application

Implement curry(fn). It returns a curried version of fn that keeps collecting arguments until it has at least fn.length of them, then calls fn with all of them. Arguments can arrive one at a time or several at once.

const volume = curry((l, w, h) => l * w * h);
volume(2)(3)(4); // 24
volume(2, 3)(4); // 24
volume(2)(3, 4); // 24
volume(2, 3, 4); // 24

const area = volume(2);
area(3)(4); // 24, and area can be reused
area(5)(1); // 10

Requirements

• Every partial application returns a new function and can be reused independently.
• Extra arguments beyond fn.length are passed through to fn.
• Calling with no arguments before enough are collected returns a curried function, it does not call fn.
• Keep the this value the final call was made with.
