Yeah, I've tried it. I've also used Adobe tools and Visual Basic before, and some web layout/theme builders. So it's the IDE plus the visual building environment, with tools for animation and what not.
I also use Jupyter Notebooks, and having a rich REPL is great for prototyping and exploration.
So maybe something like the Smalltalk environment, where the environment is a fully customizeable web browser, and the language is your choice, which would get compiled to WASM or JS.
