How to React Native Environment Setups

 There is a different alternative for React Native environment setup (installation), depends upon the operating system you use.

The instructions are quite different for each development and target operating system.

In this tutorial, we will use Windows as a development operating system and Android as a target operating system.

Developing app using React Native framework requires Node, React Native command line interface, Python2, JDK, and Android Studio.

Here, we are using a favorite package manager Chocolatey for Windows. Using this, we can install a recent version of Python, and Java SE Development Kit (JDK).
