I used that a while ago, but looks like it still alive 😊

Actually, I still think it’s the best js UI framework, at least for a browser.

Why:

• MVVM is great, much better than “state” variable like in ReactJS or Vue.
• It has nice publisher-subscriber implementation inside to serve data to controls, like “normal” ui applications for desktop.
• Controls are louse coupled, almost independant from each other, yet can communicate
• It’s tiny!

Latest realse is 2019-11-05, though.. 3 years ago, but just before covid lockdowns.
