A quite new language based on Erlang/OTP which should make it the perfect language to implement a web API. The idea is to use the Études for Elixir ebook as an outline for the exercises to get into the language. The solutions will be available on the my corresponding repository on Github.
Other things on the list include flexbox layouts (which should also help me get into CSS in general ;-), React, OAuth 2.0 and OpenID Connect.
That should pretty much keep my from being bored outside of my day job, so let’s see how this works out.
