Features requiring JavaScript code generation (like enums, parameter properties, namespaces with runtime code) need the `--experimental-transform-types` flag. + +## Decision + +We will update the TypeScript implementation to be fully compatible with Node.js Type Stripping, enabling the project to run TypeScript files directly without compilation while maintaining TypeScript's type safety
