Functional programming in JavaScript

currier.js

function curry(callable) {
	return function(...args) {
		if (callable.length <= args.length) {
			return callable.apply(null, args)
		} else {
			return curry(callable).bind(null, ...args)
		}
	}
}

// Sample Use
const sum = (a, b) => a + b
const curriedSum = curry(sum)
const addTo10 = curriedSum(10)
const totalOf15 = addTo10(5)
