Simple Enum

Provides an elegant API for non-algebraic Enumerations in javascript.

This library also provides a clever shorthand mechanism for checking the value of an enum which is very convenient for switching on properties of an enumeration.

var KEY_STATE = new Enum('UP', 'DOWN', 'JUST_DOWN', 'JUST_UP')
 
var C = KEY_STATE.JUST_DOWN
var CTRL = KEY_STATE.DOWN
 
if (C.JUST_DOWN && CTRL.DOWN) // Do copy stuff for your app

In particular, this library is more convenient and less verbose than the alternative which would look something like this

if (C === KEY_STATE.JUST_DOWN && CTRL === KEY_STATE.DOWN) // Do copy stuff for your app
