Support JSDoc parameters with properties using @param

[BrunnerLivio]

This is a suggestion/feature request for the @ts-check feature.

When using // @ts-check in a JavaScript file, TypeScript-check should be able to identify object properties types using JSDoc.

For example:

// @ts-check
/*
 * @param {Object} bar The bar object
 * @param {Number} bar.id The id of the bar object
 * @param {Object} bar.foo The foo object
 * @param {Number} bar.foo.id The id of the foo object
 */
export function Foo(bar) {
  console.log(bar.id); // TypeScript: "Holy moly it is a number"
  console.log(bar.foo.id); // TypeScript: "OMG another one"
}

Also described on JSDoc.

I hope you get the idea :)
Keep up the good work!
