About ReactJS: ReactJS is a JavaScript library responsible for providing UI components for client-side development. ReactJS has a DOM( Document Object Layer) which helps it to be faster by refreshing only some part of the page which user views. ReactJS can be used for developing dynamic network applications, ReactJS is a library for building composable user interfaces. It encourages the creation of reusable UI components that present data that changes over time. It is not a complete application framework like angular, it is just a view layer. So it is not directly comparable to frameworks like angular. https://nareshit.com/reactjs-online-training/
