React Native init specific version

Use the react-native init project_name command to initialize a React Native project. By default, the latest version of React Native is used. If you want to specify an old version of React Native, you can add --version , such as:

$ react-native init project_name --version 0.56.0
This will walk you through creating a new React Native project in /develop/project_name

or 

$ npx react-native init project_name --version 0.56.0
This will walk you through creating a new React Native project in /develop/project_name

A folder named project_name will be created in the current directory.
