Enable "useDefineForClassFields" in tsc --init

Search Terms

useDefineForClassFields, tsc --init, tsconfig

Suggestion

tsc --init's generated tsconfig.json should include "useDefineForClassFields": true

Use Cases

All major web and non-web engines now ship Define-style semantics.

So the safest approach is to ensure new TypeScript projects use standard web-compatible behavior.

Examples

It looks like we just need to add one line here. I am happy to send a PR.

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, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Inizia in src/compiler/commandLineParser.ts, vicino alla configurazione tsc --init collegata. Controlla come vengono assemblate le opzioni della tsconfig.json generata, quindi aggiungi useDefineForClassFields con il valore richiesto. Il lavoro è completato quando le configurazioni generate ex novo includono l’opzione e i controlli di generazione esistenti, se presenti, continuano a essere superati.
