CoffeeScript has the worst tooling ever.
QBasic in the 90s had better tooling than CoffeeScript: an integrated editor, debugger, compiler, type validation... let's give it all up to code in vomitscript.
But besides, judging a language based on available tooling is akin to judging a CPU based on the computer casing looks.
For a real programmer, GNU Nano with appropriate highlighting should be enough. If a language calls itself "high-level" but makes the coding process hard without tooling, it deserves no attention at all.
