The guy took out the web programming language (JavaScript) out of the web browser (V8), sprinkled with OS stuff (libuv) and there you have it, a complete programming platform a la Java, .NET, Ruby, (insert more examples here).

Node became my vanilla language nowadays. Countless are the CLI utilities that I made/use that are written with it (I practically don't write shell scripts anymore).

And of course, don't forget that networking is broader than internet which is broader than web. I'm solely talking about web here.
