О чём код?
function E () { // Keep this empty so it's easier to inherit from // (via https://github.com/lipsmack from https://github.com/scottcorgan/tiny-emitter/issues/3) } E.prototype = { on: function (name, callback, ctx) { var e = this.e || (this.e = {}); (e[name] || (e[name] = [])).push({ fn: callback, ctx: ctx }); return this; }, once: function (name, callback, ctx) { var self = this; function listener () { self.off(name, listener); callback.apply(ctx, arguments); }; listener._ = callback return this.on(name, listener, ctx); }, emit: function (name) { var data = [].slice.call(arguments, 1); var evtArr = ((this.e || (this.e = {}))[name] || []).slice(); var i = 0; var len = evtArr.length; for (i; i < len; i++) { evtArr[i].fn.apply(evtArr[i].ctx, data); } return this; }, off: function (name, callback) { var e = this.e || (this.e = {}); var evts = e[name]; var liveEvents = []; if (evts && callback) { for (var i = 0, len = evts.length; i < len; i++) { if (evts[i].fn !== callback && evts[i].fn._ !== callback) liveEvents.push(evts[i]); } } // Remove event from queue to prevent memory leak // Suggested by https://github.com/lazd // Ref: https://github.com/scottcorgan/tiny-emitter/commit/c6ebfaa9bc973b33d110a84a307742b7cf94c953#commitcomment-5024910 (liveEvents.length) ? e[name] = liveEvents : delete e[name]; return this; } }; module.exports = E; module.exports.TinyEmitter = E;
