[RxJS] Automate unsubscribe process with takeUntil

const onDestroy$ = new Subject();

fromEvent(document, 'click').pipe(
  map((event: any) => ({
    x: event.clientX,
    y: event.clientY
  })),
  takeUntil(onDestroy$)
).subscribe(v => {
  // take action
  console.log(v);
});

fromEvent(document, 'scroll').pipe(
  throttleTime(30),
  takeUntil(onDestroy$)
).subscribe(v => {
  // take action
  console.log(v);
})

interval(1000).pipe(
  takeUntil(onDestroy$)
).subscribe(v => {
  // take action
  console.log(v);
});

setTimeout(() => {
  onDestroy$.next();
  onDestroy$.complete();
}, 2000);
