React OverviewReact is a very good front-end technology.It breaks down the application into separate small modules, which are then assembled to complete the development.React is far more difficult to learn than Angularjs.React relies on a variety of tools such as Webpack to learn to use, and then focus on understanding and using ES6, before entering its core.For more information on react, please refer to th
The advent of React native has created two revolutionary innovations in mobile development: the integration of mobile app development, which not only shortens app development time, but also improves app development efficiency. Provides the foundation for mobile app dynamic updates.
