- [x] This wouldn't be a breaking change in existing TypeScript/JavaScript code
- [x] This wouldn't change the runtime behavior of existing JavaScript code

- [x] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
- [x] This isn't a request to add a new utility type: https://github.com/microsoft/TypeScript/wiki/No-New-Utility-Types

### ⭐ Suggestion

TypeScript currently only supports auto-completion for JSDoc, not TSDoc. For example, there is no intelligent suggestion for [@defaultValue](https://tsdoc.org/pages/tags/defaultvalue/).


### 📃 Motivating Example

If [TSDoc](https://tsdoc.org/) is the recommended commenting standard for TypeScript, then it should natively support intelligent suggestions and syntax highlighting for TSDoc.

### 💻 Use Cases

Writing comments using TSDoc syntax in VSCode.

Comienza investigando cómo TypeScript proporciona actualmente la autocompletación de JSDoc y cómo VSCode consume esos resultados del servicio de lenguaje. Compara ese comportamiento con etiquetas de TSDoc como @defaultValue y determina el comportamiento esperado del resaltado de sintaxis y la autocompletación; se considera completado cuando los comentarios de TSDoc reciben sugerencias inteligentes sin cambiar el JavaScript emitido.
