How do I use plug-ins like NodeJS?

Question

So all I need to start writing Javascript is a text editor and a web browser, but how do I use plug-ins like NodeJS?
Where/how do I install that?

Not recommended. Node.js is server-side javascript to handle the stuff php usually does, you don't need to dwelve into it to learn standard client-side javascript, and it would require a tutorial on its own.

That said, you can find it here: https://nodejs.org/en/download/
