Examples

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 confrontando l’opzione tsconfig.json richiesta con il comportamento esistente di tsc --showConfig. Determina come devono essere stampati la configurazione finale e il percorso di tsconfig.json, quindi aggiungi la copertura per la configurazione richiesta e l’output della console; l’issue non specifica file o test.
