One function for a new game

What we are doing

Starting a game means: build the wall, refill the lives, zero the score, serve. We collect all of it in newGame() and use it at startup.

```js
let lives
let score

function newGame() {
  buildBricks()
  lives = 3
  score = 0
  resetBall()
}

newGame()
requestAnimationFrame(loop)
```

What it means

• lives and score are declared without values; newGame() sets them.
• newGame calls buildBricks, which is written further down. That is fine: what matters is that every function is defined by the time newGame() actually runs, at the bottom.
• At the bottom, newGame() replaces the separate buildBricks() and resetBall() calls.

Your turn

1. Remove = 3 from let lives and = 0 from let score.
2. Leave an empty line under clamp and write newGame.
3. At the bottom, replace buildBricks() and resetBall() with newGame().
