Benchmark: Setting Canvas Pixel With Same Color

HTML Preparation code:

<canvas id="c" width="800" height="300"></canvas>

Script Preparation code:

$c = document.getElementById('c');
$ctx = $c.getContext('2d');
$ctx.clearRect(0, 0, 800, 300);
$px = $ctx.createImageData(1, 1);
$pxls = [];
for (var i=0; i<10000; ++i) $pxls.push({
   x: Math.random() * 800 << 0,
   y: Math.random() * 300 << 0
});
$i = 0;

Tests:

fillRect
$ctx.fillStyle = 'rgba(128, 128, 128, 1)'; for (var i=500;i--;){ var px = $pxls[$i++ % 10000]; $ctx.fillRect(px.x, px.y, 1, 1); }
1×1 Image Data
for (var i=500;i--;){ var px=$pxls[$i++ % 10000], d=$px.data; d[0] = 128; d[1] = 128; d[2] = 128; d[3] = 1; $ctx.putImageData($px, px.x, px.y); }
