In HTML canvas, you can group tiles by creating an array of objects that represent each group of tiles. Each object should contain information about the position, size, color, and any other attributes of the tiles within that group. You can then loop through the array and draw each group of tiles on the canvas using the context.fillRect() method. Here is an example of how you can group tiles in HTML canvas:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |

var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
var tiles = [
{ x: 10, y: 10, width: 20, height: 20, color: 'red' },
{ x: 40, y: 10, width: 20, height: 20, color: 'blue' },
{ x: 10, y: 40, width: 20, height: 20, color: 'green' }
];
function drawTiles() {
tiles.forEach(function(tile) {
context.fillStyle = tile.color;
context.fillRect(tile.x, tile.y, tile.width, tile.height);
});
}
drawTiles();
</script>

In this example, we have defined an array tiles that contains three objects, each representing a group of tiles with different positions and colors. The drawTiles() function loops through the array and draws each group of tiles on the canvas using the context.fillRect() method. You can customize the size, color, and other attributes of each group of tiles by modifying the objects in the tiles array.
