Benefits of React.Js

    • Rendering. When using React, it is easy to find out how a component is rendered by looking at the render function.
    • React can be rendered on the server-side. It makes the product more readable and maintainable.
    • Flexible, as it can be used with any framework (Backbone.js, Angular.js) as it is only a view layer.
    • It is easy to test, and you can also integrate some tools. This is what junior React developer would love about React.
    • Optimization: when your React app is loaded in the browser, all the components that you created are rendered.
    • React unites CSS, JavaScript and HTML are all in one component, so during creation of a React component, all three can be used in any part. So no need to create any additional external scripts and then import them.
    • React is asynchronous, so there will be no blocking actions in the app.
    • When using React feel free to install external React libraries.
    • Security. There are less XSS vulnerabilities.
