I have the same feeling. When I was a less experienced programmer, I found coffeescript to be a great tool for helping me to write 'better-looking' code while avoiding the 'bad parts' of javascript. Later, I decided to focus my expertise on javascript, learning its imperfections and beauties. Reading through parts of the sourcecode for Node.js and the popular Express.js library, I became more comfortable writing pure javascript. It now seems to me like a much more practical solution to just learn javascript and stop trying to write in a different language than the one used by the runtime

I don't know very many people who write server-side code in C or ASM, so "stop trying to write in a different language than the one used by the runtime" doesn't seem to be a very popular rule outside of the JS world either.
