Since this is just used on the line below, I would just do for (var i = 0; i < 100; i++)

yes i just copy pasted the code from the issue, i did not think of improving it.


for (var i = 0; i < I; i++) {

// shifts coordinates and rotates
rotate(0 + i * 2, 0, 1, ctx);

var color = ctx.createLinearGradient(0, 0, 200, 200);
ctx.globalAlpha = 0.1;
color.addColorStop(0, 'rgba(244, 0, 0, 0.2)');
color.addColorStop(1, 'rgba(9, 200, 0, 0.2)');
ctx.fillStyle = color;
ctx.fillRect(0, 0, 200, 200);
}
}
