Summary

When the latest React version is released, your project can be updated by changing the version to package.json and running the npm install. Make sure the react and react-dom packets always have the same version so there is no runtime conflict. For major changes, read the release notes and run the codemod when available.

Key points

Check the active version with npm list react
Update react and react-dom simultaneously
Npm install react@latest install the latest version
Codemod helps to change old APIs automatically
