getting rxjs errors when referencing latest rxjs

Update 2018/12:

RxJS v6.x introduced a new, more "functional" API. Take a look at the 5>6 migration guide for more info. The original example code still works, but you'll have to import the of operator like so:

// ESM
import { of } from 'rxjs'
// CJS
const { of } = require('rxjs');

Original RxJS 5 answer:

That's right. RxJS 5 was rewritten to improve performance and also conform to the ES7 Observable spec. Check out the RxJS 4->5 migration page on Github.

Here's a working example:

// Create new observable
const one = Observable.of(1,2,3);

// Subscribe to it
const oneSubscription = one.subscribe({
    next: x => console.log(x),
    error: e => console.error(e),
    complete: () => console.log('complete')
});

// "Dispose"/unsubscribe from it
oneSubscription.unsubscribe();

A lot of methods got renamed, but the API itself is very easy to transition to.
