What is React and React Native?

React is a JavaScript library for building user interfaces. It allows developers to create reusable UI components that can update dynamically based on data changes. React Native, on the other hand, is a framework for building mobile applications using React. With React Native, developers can write mobile apps using JavaScript and React, which are then compiled into native code for iOS and Android platforms.

Both React and React Native are popular choices for building modern, interactive user interfaces for web and mobile applications.
