When Rails 6 released I went out to:
“Rails ships with CoffeeScript by default, and so the rest of the examples in this guide will be in CoffeeScript.”
I see people leaning more towards rails as a server side / api language and less for the front end side of things and I think this contributes to that feeling.
But let me add that I’m saying this because you asked for my WTF moments. I really appreciate all the hard work the rails team puts into the project. I have been programming in rails for years and it is a beautiful framework even with the occasional bumps in the road.
