Observable.of is not a function

Question

I am having issue with importing Observable.of function in my project. My Intellij sees everything. In my code I have:

import {Observable} from          


        

Answer 1

RxJS 6

When upgrading to version 6 of the RxJS library and not using the rxjs-compat package the following code

import 'rxjs/add/observable/of';   
  // ...
  return Observable.of(res);

has to be changed into

import { of } from 'rxjs';
  // ...
  return of(res);
