# Upgrading To The Latest React In CodeSandbox

At the time of writing this, the latest version of React is 16.3.1. Opening up [CodeSandbox](https://codesandbox.io/) and starting a new React project has us working with React 16.2.

By clicking on the *circular arrow* upgrade icon next to `react` and `react-dom`, we will have upgraded each to 16.3.1.
