Introduction of React JS
Introduction of React JS 1)ReactJS is a JavaScript Library not framework as most of the people think. 2)ReactJS is used to build great UI of an App and it is not used as server side language. 3)React has a component based architecture it means it converts whole app into small components which are easy to manage and reusable. 4)React can be used by using NPM. Node and NPM should be downloded first to use react. 5)If the Node version is below 5 then we have to use NPM otherwise NPX can also be used. 6)NPX is recommended over NPM because NPX does not download the whole create-react-app into the system it only use it once. Where if we use NPM it downloads the whole create-react-app on the system.
