If you’re working with canvas shapes and want the messy part simplified, this kirupa guide on drawing shapes with functions is a solid shortcut.

It keeps the examples practical and easy to adapt, which is honestly the part most tutorials skip.

One small thing that changed canvas for me was treating every “shape function” as drawing at the origin, then positioning it with `ctx. save()`, `ctx. translate()`, and `ctx. restore()` around the call. It keeps your shape code readable because you’re not sprinkling offsets into every `moveTo/lineTo`.

```auto
function drawBadge(ctx) {
  ctx.beginPath();
  ctx.moveTo(0, -10);
  ctx.lineTo(8, 10);
  ctx.lineTo(-8, 10);
  ctx.closePath();
  ctx.fill();
}

ctx.save();
ctx.translate(x, y);
drawBadge(ctx);
ctx.restore();

```

Do they show the `save/restore` pattern in that guide, or is it mostly direct `transform` calls? I always worry people forget to reset the matrix, and everything slowly drifts.
