In 2015, React Native (RN) was born. At that time, few people paid attention to it because it was still immature with even few basic controls. Then, with the iteration of the RN project, the functions became more and more perfect. Although there has not been a release version 1.0 so far, we are delighted to find that it is the plug-in technology of Android and iOS.
Different person has different thinking.
When we put a lot of energy to study how to modify with the Android operation system source codes, they are taking another roadmap, it is to do the mapping, so that each control in Android or iOS, can find the corresponding control in the RN.
What makes RN better than Android plugins is that it also supports iOS, which maximizes cross-platform implementation. When we thought it was easy to use Android plug-in, and how to release new features to iOS, RN is a better choice.
For the performance, the difference between these two patterns is not significant. RN is very smooth on iOS and Android. Don't worry about this.
For about RN, there are already some books available. This book mainly introduces Android plug-in technology. This section shows some points that Android plug-in is not as good as RN.
