Error rxjs_Observable__.Observable.forkJoin is not a function?

Question

I am using Rxjs in an angualr-cli application.

in viewer.component.ts

    //Other Imports
    import { Observable } from \'rxj         


        

Answer 1

Use the forkJoin Operator as a function by importing forkJoin instead of importing Observable.
Use forkJoin.subscribe() in place of Observable.forkJoin.subscribe()

import { forkJoin } from 'rxjs/observable/forkJoin'

export class ViewerComponent implements OnInit, AfterViewInit, OnDestroy {
    someFunction(someArg){
      let someArray: any = [];
      forkJoin(someArray).subscribe(data => {
      });
    }
}
