How can I use RxJS merge with error handling?

You can use the merge operator in RxJS to combine multiple observables. To handle errors, you can use the catchError operator.

Can you show me a code example?

Sure! Here's a simple example:

import { merge, of, throwError } from 'rxjs';
import { catchError } from 'rxjs/operators';

const observable1 = of('Hello');
const observable2 = throwError('Error occurred!');

const merged = merge(
  observable1,
  observable2.pipe(catchError(err => of(`Caught: ${err}`)))
);

merged.subscribe(console.log);

What will this code output?

The output will be:

Hello
Caught: Error occurred!

Can I merge more than two observables?

Yes, you can merge as many observables as you want using the merge operator.
