What is the purpose of tsconfig file if typescript was not selected while project setup?

The same question is about global.d.ts.

Thanks.

tsconfig.json and global.d.ts are used by your IDE (e.g. vscode) to provide intellisense/autocompletion for your project. The main usecase in SvelteKit is to set up the path alias so that auto imports take $lib into account too. All these doesn't necessarily need typescript installed in your project because your IDE would likely have a copy built-in already.

@bluwy Thanks. I think this part worth to be explained in documentation. This is the difference between react create app, next.js and svelte kit.

Perhaps we can have some explanation under the default scaffold project readme, but I'm not too convinced if it's needed. The end-user shouldn't be removing the default files unless they know what they're doing. This discussion can serve as the explanation if they're curious though.
