How to manage the version of the React-native library _react-native

The update of the React-native library is very frequent.

So the first thing we need to know is what version of the react-native is currently in use.

How to get the current version number.

There are two ways of doing this:

1. Open the Package.json file by entering the project's root directory

You can see the version number of the react-native currently in use.

2. Use command line tools

Ditto is also the root directory of the current project.

Enter the React-native--version command to obtain the current version number.

So how do you get the information about the current react-native version number?
You can enter the command NPM info react-nartive
Get a list of the React-native libraries above NPM.

How do I manage the react-native version used for the current project after getting to the version number?

You can use the command line

NPM Install--save react-native@0.34.0

@0.34.0 represents the version number of the react-native you want to change for the current project, and the version number is obtained by just NPM info react-native.

And then you can change the version number.
