第三题：[请按照用例实现代码](https://github.com/KieSun/fucking-frontend/issues/3)
```js
// 请使用原生代码实现一个Events模块，可以实现自定义事件的订阅、触发、移除功能
const fn1 = (... args)=>console.log('I want sleep1', ... args)
const fn2 = (... args)=>console.log('I want sleep2', ... args)
const event = new Events();
event.on('sleep', fn1, 1, 2, 3);
event.on('sleep', fn2, 1, 2, 3);
event.fire('sleep', 4, 5, 6);
// I want sleep1 1 2 3 4 5 6
// I want sleep2 1 2 3 4 5 6
event.off('sleep', fn1);
event.once('sleep', () => console.log('I want sleep'));
// I want sleep
event.fire('sleep');
// I want sleep2 1 2 3
