What is combineLatest in RxJS?

Can you explain what combineLatest does in RxJS?

Sure! combineLatest is an operator in RxJS that combines the latest values from multiple observables.

How does it work with different observables?

It emits an array of the latest values from each observable whenever any of them emits a new value.

Can you give me a code example?

Of course! Here's a simple example:

import { combineLatest, of } from 'rxjs';

const obs1 = of(1, 2, 3);
const obs2 = of('A', 'B', 'C');

combineLatest([obs1, obs2]).subscribe(([num, char]) => {
  console.log(num, char);
});

This will log the latest values from both observables.

What happens if one observable completes?

If one observable completes, combineLatest will continue to emit values from the other observables until they all complete.
