2. Getting clever

Stick this inĀ Thimble:

<!DOCTYPE html>
<html>
<body>
<canvas id="canvas" width="500" height="100" style="border:1px solid #000000;"></canvas>
<script>
var canvas = document.getElementById("canvas");
canvas.style.width = '100%';
canvas.width = canvas.offsetWidth;
var context = canvas.getContext("2d");
context.font = "33px Arial";
for(var i=1; i<10; i=i+1){
context.fillText(i, i*66, 33);
if(i%2 == 0) {
context.fillText("E", i*66, 66);
}
else{
context.fillText("O", i*66, 66);
}
}
</script>
</body>
</html>

and you should get this:

[xyz-ihs snippet=”for-loop”]

Now change it and make it do even more clever stuff.
