I stopped using CoffeeScript just because JavaScript fixed most of the issues that got me to use CoffeeScript back in 2014. Once ES2015+ became well supported, I decided I'd rather write code in the language that the interpreter understands, rather than something that precompiles. CoffeeScript isn't bad... it's just not significantly better than JavaScript is today.

Also, I find it interesting how many people like the Python syntax but hate CoffeeScript syntax. They have a lot of similarities.
