The npm install experience should be baseline for newer languages. Simply let me get into hacking fast. This is one of the top reason I like tinkering with JS because it just works. (Yes, I know all weaknesses of JS ecosystem, but getting is really easy)
Please, no. Node tooling is such a mess and I can almost never get anything running easily on Nix because Node developers download binaries from the internet without understanding the system. All of these executables fail because of linked libraries. If instead they told you what libraries and executables you'd need instead loosy-goosy installing garbage all over my system, more things might work.
I think .Net has got it right. And dotnet-script [https://github.com/dotnet-script/dotnet-script] has been a game-changer for me with a REPL-like experience for unit testing and writing command-line utilities.
