It removes some features that you might\nnot need:\n\n- Domain support.\n- Thrown errors when there are no error listeners specified.\n- That a `newListener` event is emitted when an event is emitted.\n- No silly `setMaxListeners`.\n- No silly `listenerCount` function.. Just do `EventEmitter.listeners(event).length`\n\nAnd adds some features you want:\n\n- Emit events with a custom context without binding: `EE.on(event, fn, context)`\n  which also works with once `EE.once(event, fn, context)`\n\nIt's a drop in replacement of your existing EventEmitters, but just faster. Free\nperformance, who wouldn't want that.\n\nThe source of the EventEmitter is compatible for browser usage, no fancy pancy\n`Array.isArray` stuff is used, it's just plain ol JavaScript that should even\nwork IE5 if you want to. This module currently serves it's use in\n[Primus](http://github.com/primus/primus)'s client file.\n\n## Installation\n\n```bash\n$ npm install --save eventemitter3\n```\nor as a [component](http://component.io)\n\n```bash\n$ component install eventemitter3\n```\n\nthen\n\n```js\nvar EventEmitter = require('eventemitter3');\n\n// or\n\nvar EventEmitter = require('eventemitter3').EventEmitter;\n```\n\nFor API methods see the official Node.js documentation: \n\nhttp://nodejs.org/api/events.html\n",
