I didn't have to read very far: > ...they can render before JavaScript what? Because web components are written in and run on magic? > a design of composability... composing core content with HTML and then wrapping it in a custom element that enhances its contents with additional functionality Put aside the self-reference, that's not what composability usually means, but I guess that sounds fancy to the uninitiated
