fromEvent
Example 1: Observable from mouse clicks
// RxJS v6+
import { fromEvent } from 'rxjs';
import { map } from 'rxjs/operators';
//create observable that emits click events
const source = fromEvent(document, 'click');
//map to string with given event timestamp
const example = source.pipe(map(event => `Event time: ${event.timeStamp}`));
//output (example): 'Event time: 7276.390000000001'
const subscribe = example.subscribe(val => console.log(val));
