I'm React Native developer having 1.5 years of experience and recently I'm working on a project which end up a very tricky with the RN because of the performance issues especially on android while working on debug apk (Runs much better on release one). I did all the possibility optimizations as I could but still it lacks performance. After going hard through this I realise that Its very important to have atleast one Native platform experience and how much important the native development is when performance it comes to performance.
