```

//
}
const symbol = Symbol.for('symbol');
// string
EvtEmitter.Instance.subscribe('key', callback);
// number
EvtEmitter.Instance.subscribe(123, callback);
// symbol
EvtEmitter.Instance.subscribe(symbol, callback);
```
2. 触发
``` ts
// with arguments
EvtEmitter.Instance.emit('key', 'xxxxx');
EvtEmitter.Instance.emit(123);
EvtEmitter.Instance.emit(symbol);
```

EvtEmitter.Instance.unSubscribe('key');
// 解除symbol的callback监听
EvtEmitter.Instance.unSubscribe(symbol, callback);
```
