/lib/index.js:

/** @type {import('../types/index').xxx} */
function xxx() {
    return null;
}

/types/index.d.ts:

export function xxx(): string;

Cool, reproduced with:

// @allowJs: true
// @noEmit: true
// @checkJs: true

// @filename: lib/index.js
/** @type {import('../folder/index').zzz} */
function xxx() {
  return null;
}

// @filename: folder/index.d.ts
export function zzz(): string;

In normal TypeScript code, you wouldn't write import('../folder/index').zzz - but would write typeof import('../folder/index').zzz to get to the type () => string - doing this doesn't cause the loop in the code.

Which I think leads to another question, what should be the behavior here in JSDoc world? Do we assume we want the typeof to be assumed because you're using @type or does it still represent the export-ed identifier of zzz?

Asked around, and the opinion is yes - we want to pretend there's a typeof before the import in this case - gonna pair on it next week
