Why I’m Leaving Elm
I can't believe people are still complaining about something that happened almost 2 years ago for a good reason, or even about Elm not having typeclasses, or worst, for elm-format using 4 spaces, that is pointless. And I personally prefer Elm the way it is, with typeclasses the compilation speed and error messages wouldn't be the way it is now. There is already Purescript for those who need typeclasses and better js ffi, no need to follow the same path.
In the next few years Elm will have everything we need as pure elm, and libs with great quality.
