title: Online, real-time, shared JavaScript console?
body: <p>I would like to use an online tool to work remotely with people to do Javascript learning and testing exercises.</p>
  
  <p>The solution could be a shared, public Javascript console.</p>
  
  <p>Does such a thing exist? I have seen <a href="http://jsfiddle.net" rel="noreferrer">http://jsfiddle.net</a>. This works ok, but we have to keep updating our URL every time the other person changes code so it is not real-time and requires an update step on both sides.</p>
  
  <p>I think a low-feature real-time shared console would be a pretty trivial solution to build. I'm thinking of building it myself if it doesn't exist, but I wanted to check first and see if anyone has heard of something like this.</p>
