abstract-state-router/lib/promise-map-series.js

The basics of a client-side state router ala the AngularJS ui-router, but without any DOM interactions

// Pulled from https://github.com/joliss/promise-map-series and prettied up a bit

var Promise = require('native-promise-only/npo')

module.exports = function sequence(array, iterator, thisArg) {
	var current = Promise.resolve()
	var cb = arguments.length > 2 ? iterator.bind(thisArg) : iterator

	var results = array.map(function(value, i) {
		return current = current.then(function(j) {
			return cb(value, j, array)
		}.bind(null, i))
	})

	return Promise.all(results)
}
