As an Android dev, I'm confident this will become as popular as Kotlin did vs Java once it becomes stable.<p>The preview looks great, it feels like it will make a breeze out of building composable small views, which in turn will mean many small libraries will be released, and on goes the virtuous cycle.<p>As a fan of React and SwiftUI, I'm excited!
For those looking for a summary: this is a SwiftUI clone for Android. SwiftUI itself is heavily inspired by React and older Functional-Reactive-Programming frameworks.
