React JS was first introduced by Facebook in May 2013. The library was created by Jordan Walke, a software engineer at Facebook, as a solution to the company’s need for a more efficient and scalable way to build user interfaces for their web applications.
React JS was initially released as an open-source project, and it quickly gained popularity among developers due to its simplicity, flexibility, and performance. The library’s virtual DOM and component-based architecture made it easier to manage and update complex user interfaces, while its modular structure made it easier to reuse code across different parts of an application.
Since its initial release, React JS has undergone significant development, with new features and updates being released regularly. The library has also become one of the most widely used front-end web development libraries, with a large and active developer community contributing to its development and improvement.
React JS has also been adopted by many large companies, such as Airbnb, Netflix, and Instagram, who use the library to build high-performance and scalable user interfaces for their web applications.
