That's a great question! In web development, you can think of it this way: HTML is the skeleton, CSS is the skin, and Game Logic (JavaScript) is the brain.
The purpose of the game logic code in this Tic-Tac-Toe app is to handle everything that involves "thinking" or "remembering." Specifically:
- Tracking State: It remembers whose turn it is (Player X or Player O) and which squares on the board are already taken.
- Interactivity: It tells the browser what to do when a user clicks a square. Without logic, clicking a square would do nothing.
- Enforcing Rules: It prevents a player from clicking a square that is already filled or making a move after the game is over.
- Determining the Winner: After every move, the logic scans the board to see if there are three marks in a row (horizontal, vertical, or diagonal).
- Decision Making: It decides if the game should continue, if it's a draw, or if someone has won, and then triggers the appropriate message and score update.
Essentially, Game Logic turns a static drawing of a grid into an interactive game that users can actually play!
