Ha! I see I elicited the copy/paste response I’ve seen elsewhere. The gp comment I was replying to implied a JSDoc only solution (“all in JSDoc”), but given the response, clearly they’re still relying on the TypeScript language service (aka lsp plugin) to achieve type checking inside their IDE.

Wishful thinking on my part that an alternative solution for JSDoc based type checking exists :)

Do you have a particular reason to care about the implementation details of your tooling's type checker?

Generally, no. Only in the case you had a requirement to exclusively use JavaScript as the programming language you might be in for an awkward time justifying that you added type checking to the project via the type checker component of TypeScript with JSDoc :)
