Ride along with the paddle

What we are doing

While serving, the ball sits on the paddle wherever it goes. At the top of update, we keep the ball on the paddle's middle and stop there.

```js
if (state === 'serve') {
  ball.x = paddle.x + PADDLE_W / 2
  return
}
```

What it means

• === asks "is it exactly equal?". While serving, the ball's x follows the paddle's middle.
• return leaves the function at once, so the rest of update does not run.

Your turn

Write the if at the very top of update, right under function update() {, followed by an empty line.
