@JAJAX @Inginsub @meowski @alex @elaine @Kirino @bot I definitely don't start out with it on my first hack at a project, but once I have enough DTOs to throw around, I often start the project over with TypeScript so I can be more rigorous with function signatures and the like. At a certain scale, the type checking ends up saving a lot more time than it takes to manage it, but it does feel like wasted effort at the start.
