Rxjs Pipe Operator (Nothing To Be Afraid Of)

Recently i noticed following code while going through Todd Motto NGRX tutorial:

  @Effect()
  loadPizzas$ = this.actions$.ofType(pizzaActions.LOAD_PIZZAS)
   .pipe(  // <=look here!!!
    switchMap(() => {
      return this.pizzaService
        .getPizzas()
        .pipe(
          map(pizzas => new pizzaActions.LoadPizzasSuccess(pizzas)),
          catchError(error => of(new pizzaActions.LoadPizzasFail(error)))
        );
    })
  );

Since i respect Todd Motto very much i decided to look what this pipe thing is about:
After pointing on "pipe" word and clicking "F12" key (in VSCode), that is what i got:

So this pipe is rxjs one of methods which exists on Observable object, like for example toPromise or subscribe
So what is it doing?
According to Rxjs documentation :

pipe method сan be used to compose the operators in similar manner to what you're used to with dot-chaining (shown below).

Thas all - compose various operators, like "switchMap" ,"map" or "catchError" which currently (in Rxjs 5.5) could be used as standalone operators instead of methods on an observable(pipeable)

Thats IT
