What is React.js?

ReactJS is a JavaScript library used to create interactive user interfaces. It is primarily intended for use in browser-based interfaces, but can also be used to create mobile interfaces using React Native. ReactJS was introduced by Facebook in 2015 and has since gained great popularity in web development. ReactJS works by creating small components that together build a larger interface. Each component has its own logic and can be easily customized or replaced without affecting other parts of the interface. This makes ReactJS very flexible and easy to adapt to different needs. ReactJS is a powerful tool for creating interactive web interfaces, and compared to many other similar technologies, it is relatively easy to learn. Additionally, using ReactJS to create interfaces is fast and efficient, making it a very popular choice for web developers.Läs mer
