Given your skillset, I&#x27;d pick React over Scala or Docker. If you&#x27;re into PHP&#x2F;Wordpress, you could also look at Drupal 8, which was just released. Given your CSS&#x2F;JSS&#x2F;Angular skills, you could also look at Meteor for apps.<p>All that said, from a blank slate perspective, I&#x27;d suggest learning Phoenix (<a href="http:&#x2F;&#x2F;www.phoenixframework.org" rel="nofollow">http:&#x2F;&#x2F;www.phoenixframework.org</a>), and in turn Elixir. Phoenix is great framework for building moderns apps, in that it&#x27;s open source, database &amp; frontend agnostic, leveraging the battle-tested Erlang VM, highly scaleable (WhatApp built w&#x2F;Erlang), and real-time (via Channels).
