JSDoc : support @interface and @implements (and more)

I would like to re-open an issue: https://github.com/microsoft/TypeScript/issues/16142

As it is locked I am to open this new issue.

I personally do not like TypeScript as a language, I do however, like TypeScript as a tool for my JavaScript projects, hence why I would like more support for JSDoc.

Code

In a JavaScript file, with checkJs option :

/**
 * @interface Something
 */

/**
 * @function
 * @name Something#hello
 * @param {string} name
 */

/**
 * @implements {Something}
 */
const something = {};

Actual behavior:

No error.

Expected behavior:

An error should be raised. It's important in checkJs mode as JavaScript doesn't have native interfaces.

Inizia con il percorso checkJs di TypeScript per l’esempio JavaScript e analizza come vengono attualmente interpretati i tag JSDoc @interface, @implements e @function. Riproduci l’esempio, quindi definisci le diagnosi previste per l’implementazione dell’interfaccia e verificale con i test del compilatore pertinenti; il lavoro è completato quando checkJs segnala il contratto dell’interfaccia mancante.
