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.

Empieza en src/compiler/commandLineParser.ts, cerca de la configuración vinculada de tsc --init. Comprueba cómo se ensamblan las opciones de la tsconfig.json generada y añade después useDefineForClassFields con el valor solicitado. La tarea estará terminada cuando las configuraciones recién generadas incluyan la opción y las comprobaciones de generación existentes, si las hay, sigan pasando.
