What is React JS? • React JS Training- React JS basically is an open-source JavaScript library which is used for building user interfaces specifically for single page applications. It’s used for handling view layer for web and mobile apps. React also allows us to create reusable UI components. • It can be used with a combination of other JavaScript libraries or frameworks, such as Angular JS in MVC.

Why React? â&#x2013;Ş Easy to learn Anyone with a basic previous knowledge in programming can easily understand React. For react you just need basic knowledge of CSS and HTML. â&#x2013;Ş Native Approach

React can be used to create mobile applications (React Native). And React is a follows reusability, meaning extensive code reusability is supported.

…Continues… ▪ Data Binding React uses one-way data binding and an application architecture called Flux controls the flow of data to components through one control point – the dispatcher. It’s easier to debug self-contained components of large ReactJS apps. ▪ Performance React does not offer any concept of a built-in container for dependency.
