ReactJS was developed by Facebook and is considered part of the React ecosystem, which includes ReactJS (the UI library), React Native (the mobile app development framework), and React VR (virtual reality development).
ReactJS uses the "One-way Data Binding" mechanism to manage component state and provides high reusability. It focuses on creating a flexible and fast UI, enhancing development productivity and application performance.
One of the notable features of ReactJS is the Virtual DOM (Document Object Model), a copy of the actual DOM stored in memory. Instead of directly interacting with the actual DOM, React uses the Virtual DOM to update and render changes on the user interface. This improves performance and speeds up rendering in applications.
With a strong and diverse development community, ReactJS has become one of the most popular user interface development technologies today. It is widely used in both small and large projects, ranging from simple web applications to mobile and real-time applications.
With its advantages and powerful features, ReactJS is an excellent choice for building responsive, flexible, and manageable user interfaces.
