Title: I made a Logicboard.com — A collaborative code editor with code-replay feature.<p>Code-replay lets you run the coding session like a movie, I wrote a blog post on how I implemented this: <a href="https:&#x2F;&#x2F;logicboard.com&#x2F;blog&#x2F;code-replay" rel="nofollow">https:&#x2F;&#x2F;logicboard.com&#x2F;blog&#x2F;code-replay</a><p>You can try out the demo here: <a href="https:&#x2F;&#x2F;logicboard.com&#x2F;demo&#x2F;:replay" rel="nofollow">https:&#x2F;&#x2F;logicboard.com&#x2F;demo&#x2F;:replay</a><p>And play around with the code editor here: <a href="https:&#x2F;&#x2F;logicboard.com&#x2F;demo&#x2F;" rel="nofollow">https:&#x2F;&#x2F;logicboard.com&#x2F;demo&#x2F;</a><p>Logicboard also has an REPL shell, just type &quot;start()&quot; and hit enter in the output area.
