Udemy Free: Development course of a chat application with React Native

React Native is a JavaScript framework for writing real and native rendering mobile apps for iOS and Android.

It is based on React, Facebook's JavaScript library for creating user interfaces, but instead of pointing to the browser, targets mobile platforms.

In other words: web developers can now write mobile apps that truly look and feel “native”, all from the comfort of a JavaScript library we already know and love.

What's more, because most of the code you write can be shared between platforms, React Native facilitates simultaneous development for both Android and iOS.

Socket.IO is a JavaScript library for real-time web applications. Allows two-way communication in real time between clients and web servers.

It has two parts: a client-side library that runs in the browser and a server-side library for Node.js.
