how to use the onerrorresumenext function from the rxjs library in typescript

index.ts
import { of } from 'rxjs';
import { map, catchError, onErrorResumeNext } from 'rxjs/operators';

// create an observable that emits values and errors
const source$ = new Observable((subscriber) => {
  subscriber.next('value 1');
  subscriber.next('value 2');
  subscriber.error(new Error('Oops!'));
  subscriber.next('value 3');
});

// create a fallback observable that emits a value
const fallback$ = of('fallback value');

// use onErrorResumeNext operator to continue emitting values even if there's an error
const result$ = source$.pipe(onErrorResumeNext(fallback$));

// subscribe to the resulting observable
result$.subscribe(
  (value) => console.log(value),
  (error) => console.error(error),
  () => console.log('Complete')
);
