Facebook developed React JS as an open-source JavaScript library for crafting user interfaces (UIs) or UI components. Developers can leverage its capability to build reusable UI components and effectively manage the state of these components. React is a popular choice for building single-page applications or SPAs. It was first released in 2013 but the developer community expressed significant opposition to this release due to its integration of HTML, CSS, and JavaScript, which altered the approach to web development.
It introduced innovative techniques, methodologies, and utilities, such as improved runtime performance, responsive state updates, data flow via props, JSX, reusable components, and the virtual DOM. Since then it has gained widespread adoption among developers due to its flexibility, performance, and ease of use. React JS is a powerful tool for creating dynamic, scalable, and powerful user interfaces for web development.
