title: Angular 6 - Observable explanation in plain English
body: <p>I'm looking for a plain English explanation of what an Observable is in RXJS.</p>
  
  <p>What it can be used for, and any useful explanations either video links, tutorials, use cases, examples, or anything really.</p>
  
  <p>So far nothing I have found on Udemy, Todd Motto, Youtube, Angular official website has clicked with me and I just want a basic explanation of the above if that is possible.</p>
  
  <p>So far all I know is that you can subscribe to them with an observer. Is it just another kind of variable?</p>
  
  <p>Thanks in advance.</p>
