eventlistener
Just a very simple wrapper around addEventListener with a stupid fallback to attachEvent. Does not handle the differences in Internet Exploreŕs events VS standard events.
Uses Universal Module Definition, so works with AMD, CommonJS or exposed as window.eventListener.
API
var eventListener = require('eventlistener');
function onLoad(evt) {};
eventListener.add(window, 'load', onLoad);
eventListener.remove(window, 'load', onLoad);
var el = document.getElementById('test');
eventListener.add(el, 'click', function (evt) {});
