yeah defo, learning my second language was big step in my development
thanks for giving me some more motivation!
Languages with fundamentally different paradigms will still be a little tricky - Haskell, Scala, Stan, R etc don't bear a lot of resemblance to PHP.
Also, check out their learning paths for C# - it can be a good option to avoid the overwhelm if you are new to the language.
As someone super rusty on it, I found it remarkably easy to get up and running on the platform.
If they can only finish the tooling so that NCrunch can run properly, life will be a bliss.
The examples are in .NET Core (the cross-platform parts are more Mac than Linux focussed) but really it's a general guide on how to make web applications perform well.
