Since you can add type annotations in typescript, it does not use JSDoc for types. This is by design.
You need to use nonPrimitive: string instead.

IIRC there's a quickfix that converts JSDoc types to type annotations.

In some cases my project team can't use the compile tools , And now I have a problem in vue typescript component , in .ts file the vue component this type is right, but if I rename the extname .ts to .js, this vue component this type is any.
Because typescript is a superset of javascript, so only write javascript is good, but I found I can't define type by jsdoc, it bothered me and make me write javascript without typescript help as before .

yeah, I find out jsdoc since begin is design for js not ts , so ts file can't use jsdoc to define type .
