Redux Selector Pattern

Imagine we have a reducer to control a list of items:

function listOfItems(state: Array<Object> = [], action: Object = {}): Array<Object> {
  switch(action.type) {
    case 'SHOW_ALL_ITEMS':
      return action.data.items
    default:

This is a recursive version of PHP's ksort function.

	// To ensure cross-browser support even without a proper SubtleCrypto
	// impelmentation (or without access to the impelmentation, as is the case with
	// Chrome loaded over HTTP instead of HTTPS), this library can create SHA-256
	// HMAC signatures using nothing but raw JavaScript

	/* eslint-disable no-magic-numbers, id-length, no-param-reassign, new-cap */

	// By giving internal functions names that we can mangle, future calls to
	// them are reduced to a single byte (minor space savings in minified file)
	var uint8Array = Uint8Array;
