compiler.extends extends

✅ 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

After merging https://github.com/microsoft/TypeScript/pull/50403, the docs at https://www.typescriptlang.org/tsconfig/#extends haven't been updated to indicate that extends may be an array.

📃 Motivating Example

Users may only learn that extends may be an array if they find the PR above.

Beginne auf der tsconfig-Referenzseite für compilerOptions.extends und prüfe den verlinkten TypeScript-PR #50403 auf das unterstützte Verhalten. Aktualisiere die Dokumentation so, dass angegeben wird, dass extends ein Array sein kann, und überprüfe anschließend, dass die gerenderte Seite dies eindeutig widerspiegelt, ohne andere Konfigurationshinweise zu ändern.
