How to import Observer with ForkJoin in RXJS 6.3.3?

Question

I tried:

import { Observable } from "rxjs/Observable";
import 'rxjs/add/observable/forkJoin';

It says: module Observable has no imported, also does not work map for fork:

return Observable.forkJoin([
      this.loadCompanies(),
      this.loadUsers(),
      this.loadEvents()
    ]).map((data: any[]) => {});

forkJoin is a stand-alone factory function and imported as import { forkJoin } from 'rxjs';

I tried `import { forkJoin } from 'rxjs';` it does not support map for fork – Feb 04 '19 at 20:38

again, `map` is a standalone factory function which must piped, i.e., `forkJoin().pipe(map(...));` – sellmeadog Feb 04 '19 at 20:38
So, to use map I must import also: `import { map } from 'rxjs/operators';`? – Feb 04 '19 at 20:43
Yes. You must import all of the pipeable operators that were on the prototype in rxjs 5. – sellmeadog Feb 04 '19 at 20:50
