Strongly Typed Events - Signals

Signals are the most barebone of all events. They don't contain
any data. They just invoke the registered handler.

An example says more than a 1000 words. Imagine if you have events like this on your class:
``typescript
let clock = new Clock("Smu", 1000);

//log the ticks to the console - this is a signal event
clock.onTick.subscribe(() => console.log("Tick!"));

`

So let's look at the implementation from a TypeScript perspective. (Do you program NodeJs without typescript? Check this)

`typescript
import { SignalDispatcher } from "ste-signals";

class Clock {
private _onTick = new SignalDispatcher();
private _ticks: number = 0;

constructor(public name: string, timeout: number) {
setInterval(() => {
this._ticks += 1;
this._onTick.dispatch();
}, timeout);
}

public get onTick() {
return this._onTick.asEvent();
}
}
``
