MobX

Edit This Page This are utilities exposed by MobX which might come in handy at some point. But most probably you won't need them. Ever.

SimpleEventEmitter

Constructorless class that can be used to register and emit events. Mainly here for internal purposes.

```javascript const eachSecondEvent = new mobx.SimpleEventEmitter();

setInterval(() => { eachSecondEvent.emit(new Date(), Date.now()); }, 1000);

// fires each second eachSecondEvent.on((dateObject, epoch) => { console.log(dateObject, epoch); });

// fires only once eachSecondEvent.once((dateObject, epoch) => { console.log(dateObject, epoch); });
