title: Can't find `combineLatest` in RxJS 5.0
body: <p>The following code it's causing me a <code>Observable.combineLatest is not a function</code> using RxJS 5.0:</p>
  
  <pre><code>let Observable = require('rxjs/Observable.js').Observable;
  import 'rxjs/add/operator/combineLatest';
  
  Observable
  .combineLatest([player, spaceShip], (shotEvents, spaceShip) =&gt; ({
      x: spaceShip ? spaceShip.x : board.canvas.width / 2,
      timestamp: shotEvents.timestamp
  }))
  </code></pre>
  
  <p>All other Observables are able to be resolved, the only function not being resolved is my <code>combineLatest</code>. I tried <code>observables/combineLatest</code> just for the sake of trying to no avail.</p>
  
  <p>I'm compiling everything using <code>webpack</code> and <code>babel</code>, and the code is able to resolve <code>scan</code>, <code>range</code>, <code>interval</code>, <code>map</code>, and some others. Even <code>flatMap</code> using <code>import 'rxjs/add/operator/mergeMap';</code> worked. </p>
  
  <p>But not <code>combineLatest</code></p>
  
  <p>So if anyone has a working example it would be deeply appreciated. Couldn't find anything else in the docs besides <a href="https://github.com/ReactiveX/RxJS/blob/master/spec/operators/combineLatest-spec.ts" rel="noreferrer">a unit test that is basically the same thing (an array of observables and a function).</a></p>
  
  <h1>UPDATE APR 04 2018</h1>
  
  <p>On RxJs 5.5 use the following:</p>
  
  <pre><code>import { combineLatest } from 'rxjs/observable/combineLatest'
  </code></pre>
  
  <p>Moving forward (RxJs 6) use the following:</p>
  
  <pre><code>import { combineLatest } from 'rxjs'
  </code></pre>
