# Overview
With the rapid development of the mobile Internet, pure native development can no longer meet the needs of business that grows rapidly. The cross-end solution can not only cope with fast iterative business needs, but also improve the code reuse rate and reduce development costs, thus becoming the first choice of many companies.
React Native (opens new window) is a cross-platform mobile application development framework open sourced by Facebook in April 2015, and is a derivative of Facebook’s earlier open source UI framework React in the native mobile application platform, currently supporting iOS and Android platforms. React Native uses JavaScript language and HTML-like JSX and CSS to develop mobile applications, and developers familiar with web front-end development can quickly get started with a little time spent learning.
