React Native and Kotlin are both popular choices for mobile app development, but they have their own strengths and weaknesses.
Kotlin, on the other hand, is a programming language that was designed to improve upon Java. It is now officially supported by Google as a first-class language for Android app development. It is a more expressive and concise language than Java, and it also has improved type inference and null safety.
One major advantage of Kotlin over React Native is that it can be used for both Android and iOS development. With React Native, you need to maintain two separate codebases for each platform, whereas with Kotlin, you can share more code between the two platforms.
