Question

I’ve made a code but i cant get it zoom in:

function drawMap() {
    var tileH = 31;
    var tileW = 61;
    for (i = 0; i < map.length; i++) {
        for (j = 0; j < map[i].length; j++) {
            var drawTile = map[i][j];
            var xpos = (i - j) * tileH + mapX;
            var ypos = (i + j) * tileH / 2 + mapY;
            ctx.drawImage(tileImg[drawTile], xpos, ypos);
            if (i == xmouse && j == ymouse) {}
        }
    }
}

How can i get this zoomed in using javascript?
