Node.js function metadata for code completion

Question

So, the core of my problem is that I might not know what the thing I want is called. I think it's called "metadata", but Google doesn't turn up anything. Anyway when you type a function's name in WebStorm (though I can not imagine this being unique to it) it will sometimes display a tooltip, telling you what the function does and what parameters it takes- this really cuts down the time needed to look stuff up. So, I want to bundle those with the functions I write. How do I do that, or at least what is it properly called?

There isn't one term for it, unfortunately. Microsoft's term is "IntelliSense." Various other terms are listed in this answer on programmers.stackexchange.com :

• Auto Code Completion
• Code Completion
• Code Hinting
• Code Assist

I believe the term they use at JetBrains (the people behind WebStorm and IntelliJ and such) is "Code Completion," based on the WebStorm help .

More about WebStorm code completion on their blog . It looks like they'll work from the source code, using JSDoc if they find it.
