Javascript debugging [slightly] beyond console.log

We could give any name to the Square’s onClick prop or Board’s handleClick method, and the code would work the same. In React, it’s conventional to use on names for props which represent events and handle for the methods which handle the events. We recommend that you check out the tic-tac-toe game before continuing with the tutorial. One of the features that you’ll notice is that there is a numbered list to the right of the game’s board. This list gives you a history of all of the moves that have occurred in the game, and it is updated as the game progresses. This tutorial is designed for people who prefer to learn by doing.

• The mobile flashcards are the perfect way to wake up in the morning.
• Object Properties – dive into the object’s properties and their attributes.
• JavaScript Hello World – learn how to execute the first JavaScript code that displays the famous “Hello, World!” message.
• HTML can only create webpage structure, css can style html, but to add functionality, we need javascript.
• Kenny is the Domain Manager for the Web Development Domain at Codecademy.

Finally, we need to move the handleClick method from the Board component to the Game component. We also need to modify handleClick because the Game component’s state is structured differently. Within the Game’s handleClick method, we concatenate new history entries onto history. We’ll want the top-level Game component to display a list of past moves. It will need access to the history to do that, so we will place the history state in the top-level Game component.
