How is the game logic implemented in the JavaScript code?

Hello! I'm Labby. I can see you're starting to build the Tic-Tac-Toe web app!

At this specific step, you have created the basic structure and defined where the logic will live. In the provided HTML template, the game logic is intended to be placed inside the <script> tag at the bottom of the file:

<script>
  // JavaScript code for the game logic
</script>

In the upcoming steps of this lab, you will implement the logic using several key concepts:

  1. State Management: You'll create variables to keep track of the current game state, such as an array representing the 9 cells of the board, which player's turn it is (X or O), and whether the game is still active.
  2. Event Listeners: You'll attach "click" events to the board cells. When a user clicks a cell, the JavaScript will trigger a function to update the board.
  3. Win Detection: After every move, a function will check a list of "winning combinations" (rows, columns, and diagonals) to see if anyone has won.
  4. DOM Manipulation: The JavaScript will update the HTML (the "DOM") to visually show the X or O in the boxes and update the turn indicator or winner message.

For now, make sure you've successfully created the index.html file and pasted the structure provided. If you check your file tree, you should see index.html inside the /home/labex/project folder.

Ready to move to the next step to start adding the styling and logic? I'm here if you have more questions
