+/// Module detection mode
+///
+/// This setting controls how TypeScript determines whether a file is a script or a module.
+/// These choices include:
+///   - "auto" (default) - TypeScript will not only look for import and export statements, but it will also check whether the "type" field in a package.json is set to "module" when running with module: nodenext or node16, and check whether the current file is a JSX file when running under jsx: react-jsx.
+///   - "legacy" - The same behavior as 4.6 and prior, usings import and export statements to determine whether a file is a module.
+///   - "force" - Ensures that every non-declaration file is treated as a module.
