Pixels array p5.js vs java improving speed

[quark]

Changing the draw method to

function draw() {
  p++;
  loadPixels();
  let t = pixels;
  for (let i = 0; i < t.length; i += 4) {
    c = k[(a[i] + p) & 127];
    t[i] = c._getRed();
    t[i + 1] = c._getGreen();
    t[i + 2] = c._getBlue();
    t[i + 3] = 255;
  }
  updatePixels();
}

will save a few bytes
