Avoid Typing Twice When Defining Action Names
Found a nice package which can help defining actions a lot easier by avoiding type the key/value twice when defining action names.
The package is KeyMirror. Simply import it into the source code and then you can build a dictionary with key/value pairs are of the same values.
var keyMirror = require('keyMirror');
var COLORS = keyMirror({blue: null, red: null});
var myColor = COLORS.blue;
var isColorValid = !!COLORS[myColor];
