We can set this default by modifying the initial state in our Board constructor:. In addition to taking input data accessed via this.
We now need to fix an obvious defect in our tic-tac-toe game: The next step is to get our app to handle data. And similarly, the LastNameField:. This section will introduce you to the powerful, but less commonly used React features like context and refs. There are generally two approaches to changing data. Sign in Get started.

Here are the required steps to transform the Board component:. Mastering React Functional Components with Recompose. Facebook has created a Create React Application with everything you need to build a React app. You now have a working tic-tac-toe game. When we render a list, React stores some information about each rendered list item. The status of the Reactje sub-projects used to be available in the project wiki. Sometimes people find third-party books and video courses more helpful than the official documentation.
This might take a couple of minutes. This tutorial has gotten a little longer than I was expecting. Now, to start reacths application:.
