Java (and Object Pascal, I’m assuming) have very old-looking UIs. Discord’s gonna have trouble attracting users if their client looks like a billing system from 2005. Also, what do you do about the web client? Implement the UI once in HTML/CSS/JS, and again in JForms?
So if you’re picking one UI to make cross-platform, and you need a web client, do you pick JForms and make it work on the web? or React and make it work on desktop?
Isn’t jfx still actually using HTML and CSS, though? like it’s cool that the UI logic is in Java, but doesn’t using CSS mean you still need to lug a rendering engine around, even if not a whole browser?
