title: How to stop an interval on an Observable in RxJS
body: <p>I have a specific situation where I'm using an RxJS interval, but at any given moment I may need to stop that interval. I assumed there was something easy like a cancel() or stop(). Similar to clearTimeout. This is possible to stop an interval once it's going? If not, what would be another approach.</p>
  
  <p>Basically I have a large array that I'm stepping through. But there are external things that could happen that make it necessary to stop that step through and continue on to a new task. I'm hoping it's something simple that I'm just missing in the docs. Thanks </p>
