Promise.all alternative in RxJS

import { ajax } from 'rxjs/ajax';
import { of } from 'rxjs';

const myObs = of([
  ajax('https://jsonplaceholder.typicode.com/users/1'),
  ajax('https://jsonplaceholder.typicode.com/posts/1')
]);
// now myObs is of the type Observable<Observable<AjaxResponse>[]>
// for some reason I don't feel too good about this

myObs.subscribe(function(value) {
  /**
   * here I get an array of 2 observables which I have to
   * loop over and subscribe to each of the observables
   */
  console.log('emitted value:', value);
})
