NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

Trial ?

If we want animations in React Native applications, React Native Reanimated 2.0 is the way to go. We previously had Reanimated 1.x, but it had issues related to the complexity of the Reanimated declarative language and also had some additional performance costs related to initialization and communication between the React Native JavaScript thread and the UI thread. Reanimated 2.0 is an attempt at reimagining how to run animations in the UI thread; it allows us to code the animations in JavaScript and run them on the UI thread using a new API called animation worklets. It does this by spawning a secondary JavaScript context on the UI thread that then is able to run JavaScript functions. We're using it in our React Native projects which need animations and like it a lot.
