Show code comments in union types

Suggestion

When I use union types in Typescript, the annotations of the types are missing and cannot be given. I would like to be able to show some code its meaning with the help of annotation hints.

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

📃 Motivating Example

💻 Use Cases

Inizia con l’esempio collegato di TypeScript Playground e verifica come sono rappresentate le annotazioni dei tipi unione visualizzate. Chiarisci la sintassi dei commenti prevista, l’ambito degli strumenti interessati e i casi d’uso prima di identificare le posizioni dell’implementazione e dei test. Il lavoro è completo quando le annotazioni per i membri dell’unione possono essere scritte e visualizzate senza modificare il JavaScript emesso.
