Function.prototype.bind is slow in JS, so we fix it plus we have great compatibility (at least for 90% of common cases without partial args)

fast-bind.js

+function(proto, Object) {
	'use strict'
	var originalBind = proto.bind
	Object.defineProperty(proto, 'bind', {
		value: function bind(context) {
			var callback = this
			return arguments.length === 1 ? function () { return callback.apply(context, arguments) } : originalBind.apply(callback, arguments)
		}
	})
}(Function.prototype, Object)
