angular add debounce time before putting valu in subject next

import {Component}   from '@angular/core';
import {FormControl} from '@angular/forms';
import {Observable}  from 'rxjs/Observable';
import 'rxjs/add/operator/debounceTime';
import 'rxjs/add/operator/throttleTime';
import 'rxjs/add/observable/fromEvent';

@Component({
  selector: 'my-app',
  template: `
    
{{firstName}}` }) export class AppComponent { firstName = 'Name'; firstNameControl = new FormControl(); formCtrlSub: Subscription; resizeSub: Subscription; ngOnInit() { // debounce keystroke events this.formCtrlSub = this.firstNameControl.valueChanges .debounceTime(1000) .subscribe(newValue => this.firstName = newValue); // throttle resize events this.resizeSub = Observable.fromEvent(window, 'resize') .throttleTime(200) .subscribe(e => { console.log('resize event', e); this.firstName += '*'; // change something to show it worked }); } ngDoCheck() { console.log('change detection'); } ngOnDestroy() { this.formCtrlSub.unsubscribe(); this.resizeSub .unsubscribe(); } }

Here is what the above code is Doing:
1. The firstNameControl is a FormControl that is bound to the input element.
2. The firstNameControl.valueChanges observable is subscribed to.
3. The debounceTime operator is used to delay the emission of the valueChanges observable.
4. The subscribe method is used to update the firstName property.
5. The Observable.fromEvent method is used to create an observable from the window resize event.
6. The throttleTime operator is used to delay the emission of the resize event observable.
7. The subscribe method is used to update the firstName property.
