ReactJS

Welcome

React is front end library developed by Facebook. It's used for handling viewlayer for web and mobile apps. ReactJS allows us to create reusable UI components. It is currently one of the most popular JavaScript libraries and it has strong foundation and large community behind it.

React Features

• JSX − JSX is JavaScript syntax extension. It isn't necessary to use JSX in React development, but it is recommended.
• Components − React is all about components. You need to think of everything as a component. This will help you to maintain the code when working on larger scale projects.
• Unidirectional data flow and Flux − React implements one way data flow which makes it easy to reason about your app. Flux is a pattern that helps keeping your data unidirectional.
• License − React is licensed under the Facebook Inc. Documentation is licensed under CC BY 4.0.

React Advantages

• React uses virtual DOM which is JavaScript object. This will improve apps performance since JavaScript virtual DOM is faster than the regular DOM.
• React can be used on client and server side.
• Component and Data patterns improve readability which helps to maintain larger apps.
• React can be used with other frameworks.

React Limitations

• React only covers view layer of the app so you still need to choose other technologies to get a complete tooling set for development.
• React is using inline templating and JSX. This can seem awkward to some developers.
