I cringe everytime my manager tells me not to write shell scripts but javascript instead. There is ShellCheck, Bats and there are extensions for e.g. Visual Studio Code or Jetbrains IDEA that make writing shell and bash scripts a pleasure. I find it generally much more productive to write a shell script because I already know all the gnu/unix userland tools. And i know this shell script will be portable and still running decades from now unless some version specific node script with dependencies.
