How CodeCombat Was Built

I love codecombat. I love how these guys started out like me with hardly any understanding of what different frameworks do. And yet, they went and make something so amazing.<p>Just a little nitpick: Does anybody else find the redundant &quot;like&quot; annoying? It doesn&#x27;t matter as much when you&#x27;re talking but it makes reading it, rather annoying. Perhaps the editors should have refined that

What are they using Firebase for?<p>Great read anyway. I always feel inferior when I see other companies&#x27; tech stacks but this makes me realize you can learn along the way and still be successful.

It&#x27;s a nice problem we have that there are several programming games out there that I keep confusing them...my first thought was that CodeCombat was the $170K Kickstarter that ran into some drama last year...but that is Code <i>Hero</i>. Does anyone know how it&#x27;s doing?
