I am very much impressed with concepts of Scala (also Dotty), lovely to learn. But I feel like everybody think it is hard language to learn. Before proceeding with new concepts, I would recommend to improvise easy documentation for Scala 3 to reach wide audience (also IDE support).
I recently come across site https://javascript.info/. It was very pleasant to learn each and every concepts of Javascript, simple & detailed manner. Loved it.
Please consider similar documentation for Scala 3.
