import { Observable, merge } from 'rxjs'; const obs1$ = Observable.from([1, 2, 3]); const obs2$ = Observable.from(['a', 'b', 'c']); const obs3$ = Observable.from([{name: 'John'}, {name: 'Jane'}]); const merged$ = merge(obs1$, obs2$, obs3$); merged$.subscribe(val => console.log(val));In this example, we create three observables - `obs1$`, `obs2$`, and `obs3$`, each emitting different types of values. We then use the `merge` operator to combine them into a single observable stream called `merged$` which emits all values from all source observables. Finally, we subscribe to `merged$` and log the emitted values to the console. The library for this example is `rxjs`.
