Generation background
Because React’s design idea is extremely unique, it is a revolutionary innovation, has outstanding performance, and the code logic is very simple. Therefore, more and more people are beginning to pay attention to and use it, thinking that it may be the mainstream tool for web development in the future.

The derived React Native project has even more ambitious goals. It hopes to write Native App in the same way as Web App. If it can be realized, the entire Internet industry will be subverted, because the same group of people only need to write the UI once and it can run on the server, browser and mobile phone at the same time.
