Answer by Len for Document collection (array of type) return value and parameter in JSDoc

Although you may find that the guidance given in some of the other answers works for you, I prefer this syntax:

/** * @return {Array<String>} ... */

And in comparison to the guidance others have offered, I think this is closer to your expectation based on the example you give in your question.

Here's great source for information on JSDoc:https://wiki.servoy.com/display/DOCS/JSDoc+Annotations
