Reverse-engineering Promise (loosely)

	// This is a very bare-bones (and incomplete) implementation of the idea
	// behind Promise, using a new function called Commitment:

	const Commitment = function(func) {
	this.state = 'PENDING' // will be changed to 'FULFILLED' or 'REJECTED'

	const resolve = (result) => {
	this.state = 'FULFILLED'
	this.resolver && this.resolver(result)
	}
