Is anybody else on having success with JavaFX replits?

Does anybody here use for JavaFX? I can’t get the replit to work properly, and was wondering if anyone else is using it, and if so, can you get autocompletion to work? How about document formatting? For me, neither work.

From a quick google search, javaFX seems to be a desktop (and mobile?) application maker. Although replit might support this, it is probably more optimal to just use a computer.

I don’t really use javafx, could you provide a small example/recording?

Thanks for your reply, @dragonhunter1.

Here’s a link to what I’m seeing.
