✅ Viability Checklist

• 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 isn't a request to add a new utility type: https://github.com/microsoft/TypeScript/wiki/No-New-Utility-Types
• This feature would agree with the rest of our Design Goals: https://github.com/Microsoft/TypeScript/wiki/TypeScript-Design-Goals

⭐ Suggestion

For the following case, TypeScript 5.5.3 throws "A 'set' accessor cannot have a return type annotation."

interface Foo {
  set foo (value: number): void
}

the 'void' is a special type , 'set' accessor should be allowed to return it.
Because I think in TS "Every function should/could have a return value , if it don't, please return void ."

📃 Motivating Example

I think , in a ts project , there should be a Uniform code specification, like this :
"All functions have return type , or All functions don't have return type, no exception" .

💻 Use Cases

make my project under a Uniform code specification.

L’issue non indica alcun file sorgente, test o punto di ingresso del compilatore. Inizia riproducendo la diagnostica di TypeScript 5.5.3 con l’esempio di interface e traccia il modo in cui vengono controllate le annotazioni del tipo restituito dei setter. Il lavoro è completato quando un’annotazione void viene accettata senza modificare il JavaScript emesso né il comportamento esistente a runtime.
