alt Hacker NewsThis year I also switched from Ruby to Kotlin on my hobby/light commercial backends. I just can't stand the way Ruby is not statically typed, and the resulting insecurity around if everything is actually doing what it should do. Kotlin gives me joy, and performance is actually better (trading memory requirements ofcourse, but that's not a big problem anymore). I still love Ruby, but only use it for simple scripts now.
This has sort of been my issue with Elixir. I've been doing Scala for years but I think Phoenix is really the best web story at the moment for how I want to be building web apps. And while I believe that the benefits of static typing somewhat decrease in the web arena, it's still frustrating to have to manage type relationships in my head.
I'm hopeful that the incoming type system work makes me happier there, though I'd also prefer a nicer editor experience than is currently available.
