make a tic tac toe game in javascript

To make a simple tic tac toe game in JavaScript, we can start by creating a 3x3 grid on the web page using HTML and CSS. We can use the div tags to represent each cell of the grid. We can also assign unique IDs to each cell to easily identify them in JavaScript.


index.tsx
<div id="cell-0"></div>
<div id="cell-1"></div>
<div id="cell-2"></div>
<div id="cell-3"></div>
<div id="cell-4"></div>
<div id="cell-5"></div>
<div id="cell-6"></div>
<div id="cell-7"></div>
<div id="cell-8"></div>

Next, we can use JavaScript to handle the game logic. We can store the current state of the game in an array and update it based on the moves made by the players. We can also use the CSS classes to change the appearance of the cell based on the current state of the game.


index.tsx
// Initialize the game state
var gameState = ["", "", "", "", "", "", "", "", ""];

// Handle the player move
function playerMove(cell) {
  // Update the game state
  gameState[cell] = "X";
  // Update the cell appearance
  document.getElementById("cell-" + cell).classList.add("player");
  // Check if the player won
  checkWin("X");
  // Let the computer make a move
  computerMove();
}

// Handle the computer move
function computerMove() {
  // TODO: Implement the computer AI
}

// Check if the given player has won
function checkWin(player) {
  // TODO: Implement the win checking logic
}

Finally, we can add event listeners to the cells to allow the players to make their moves by clicking on the cells.


index.tsx
// Add event listeners to the cells
for (var i = 0; i < 9; i++) {
  document.getElementById("cell-" + i).addEventListener("click", function() {
    playerMove(i);
  });
}
