RxJs catch error and continue

Question

I have a list of items to parse, but the parsing of one of them can fail.

What is the \"Rx-Way\" to catch error but continue executing the sequence

Code Samp

To keep your endlessObservable$ from dying you can put your failingObservable$ in a higher-order mapping operator (e.g. switchMap, concatMap, exhaustMap...) and swallow the error there by terminating the inner stream with an empty() observable returning no values.

Using RxJS 6:

endlessObservable$
    .pipe(
        switchMap(() => failingObservable$
            .pipe(
                catchError((err) => {
                    console.error(err);
                    return empty();
                })
            )
        )
    );
