CoffeeScript is ES6+ with a bit more expression-ness, less punctuation, and fewer new features like async/await. CoffeeScript's grammar and compiler have always been a bug-ridden mess (a fix was my first open source contribution), while for ES6+ you have three different well-supported sanely-engineered cross-compilers, as well as native support in browsers, and support from every development tool made in the last few years.
I loved CoffeeScript in 2012, but even then it was clearly a stop-gap, and we're on the other side. You're putting yourself at a strict engineering and hiring disadvantage, in return for... having less punctuation so you feel better about writing markup in your JavaScript..?
