The main reason behind React Native’s popularity is its ability to build cross-platform apps.
You have to write the code once and then render it on various platforms natively.
When Facebook released the framework in 2015, it was one of the few cross-platform app development platforms available.
Over the years, Facebook engineers have added multiple features to make it one of the preferred choices.
Besides the strong community support, here are some more reasons behind React Native’s popularity:
Reusable and sharable code
Wide range of third-party plugins available
Easy and quick prototyping
