I like I can build almost anything with it, from web applications to command line to desktop applications, to embedded scripts in almost any service. I love it is asynchronous by default (and thus all its ecosystem is as well). As someone that had to deal a lot with thread pools, and semaphores and concurrency issues, this is invaluable to me. I also like a lot the tooling. From VSCode support, to typescript, to eslint, prettier and despite people complain about large node_modules, I think NPM and the trade offs leading to that are very worth it. I also really enjoy the availability of libraries... whatever you need, you'll find a popular package for it.
