The answer
compose, pipe, curry, partial, memoize, debounce, throttle, and once. All rely on closures and first-class functions. They are the building blocks of functional programming in JavaScript.

compose applies functions right to left: compose(f, g)(x) = f(g(x)). pipe applies functions left to right: pipe(f, g)(x) = g(f(x)). pipe is more natural to read (first function runs first).
Return a function that collects arguments. If enough arguments are collected (args.length >= fn.length), call the original function. Otherwise, return a new function that collects more arguments. Use recursion.
curry transforms a function into a chain of single-argument functions: f(a)(b)(c). partial presets some arguments and returns a function for the rest: f'(b, c) with a preset. curry is one-arg-at-a-time; partial is some-args-now.
