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 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

Uses virtual DOM which is a JavaScript object. This will improve apps performance, since JavaScript virtual DOM is faster than the regular DOM.

Can be used on client and server side as well as with other frameworks.

Component and data patterns improve readability, which helps to maintain larger apps.

React Limitations

Covers only the view layer of the app, hence you still need to choose other technologies to get a complete tooling set for development.

Uses inline templating and JSX, which might seem awkward to some developers.
