Expected result

As the import is referenced in the JSDoc, it should not be flagged as an unused import.

Removing this import causes tsc to complain (rightfully) that it doesn't know what type this is. (tsc checking JS files). This happens a lot when you are passing a certain type to a function, but never need to create it. You never explicitly reference the typename but access its properties.

Thanks, this seems like a valid request.

Please be aware though that we currently don’t do any analysis on JsDoc comments, so this is unlikely to be picked up soon unless someone wishes to contribute such support.

As a workaround, I would suggest moving the import itself into a comment as well. I believe tsc supports some syntax to do this.
