How can I use RxJS merge in my Angular application?

You can use the merge operator from RxJS to combine multiple observables into one. This is useful for handling multiple streams of data.

Can you show me a code example?

Sure! Here's a simple example:

import { merge } from 'rxjs';
import { map } from 'rxjs/operators';

const observable1 = of('Hello');
const observable2 = of('World');

const merged = merge(observable1, observable2);

merged.subscribe(value => console.log(value));

What if I want to handle errors in the merged observables?

You can use the catchError operator within each observable before merging them. This way, you can handle errors individually.

Thanks! Is there a way to limit the number of emissions?

Yes, you can use the take operator to limit the number of emissions from each observable before merging.
