Except Fortran and Cobol are pretty much alive, with ISO still releasing languages updates, recently LLVM got a Fortran compiler, supported by the likes of ARM and NVidia.
They are just "dead" in that they are specialized programming languages with a domain of their own, that magpie developers don't find attractive to put on their CV.
CoffeeScript in 2020 is just legacy code that one wants to get rid of, because some juniors found it cool to smuggle into the IT infrastructure.
Opinions are fine, I don’t like CoffeeScript and never have.
It’s no justification to shame someone’s choices when perfectly well working code is usable via what appears to me to be a healthily maintained tool. Less popular? Sure. Would I reach for it to start a new project? no.
Calling it dead though and saying it’s only around because it’s “legacy” and only was used by “cool IT juniors” is shaming a legitimate choice without giving any context or data to back up the assertions
