The IDE tells you what's needed and the latest version of the plugin automatically adds a list literal and places the cursor inside it:

Personally, I think it makes sense to differentiate between exactly one and zero or more.

The IDE should do that for you.

Fail. IDE dependence is an anti-pattern and a programmer-smell.

Either the IDE/editor is able to assist you or you have to consult the documentation regularly.

That's just how it is.

JS' standard library, for example, is really tiny but I haven't memorized all of it. If the editor can't clue me in, I have to check the docs.

Nothing wrong with doing any of it, as long as its a dependency you can manage while also maintaining productivity... but such is the life of a Javascript developer.
