rxjs 6 Property 'of' does not exist on type 'typeof Observable'

Question

Just moved from rxjs 5/angular 5 to rxjs 6/ angular 6, went through this migration-guide. Can't seem to figure out what it should be now, any help appreciated.

import { Observable, of } from 'rxjs'; [ts] 'of' is declared but its value is never read.  // trivial example of what im trying to replace   isLoggedIn(): Observable<boolean> {     return Observable.of(true);   } 

Answer 1

You can now just import of from rxjs. So....

import { Observable, of } from 'rxjs';  // trivial example of what im trying to replace   isLoggedIn(): Observable<boolean> {     return of(true);   } 

Answer 2

If you are using Angular 6 /7 or 9

import { of } from 'rxjs'; 

And then instead of calling

Observable.of(res); 

just use

of(res);
