I really like this idea. Brings back the good feeling I would get with CoffeeScript's syntax being shorthand for what I would write in JS but targeted at TS. I hope this stays around and gets some traction.

Me too! I've been porting over some of my Coffee projects into Civet and fixing issues as I encounter them. It's getting better all the time.

I have been searching in the past for such a project. Great initiative

Cool project! It’s cool to read thru the list of what you’ve added from Coffeescripts behaviour and not. Reminds me of some things I still miss from Coffeescript!
