Reanimated 4 brings a CSS animation API for React Native, reworks state animations and adapts worklets and the behavior of Spring animations.

With the release of Safari 13.1, the Web Animations API now ships with all evergreen browsers. Early animations in web browsers were typically created with JavaScript APIs.
