Draw the keys

What we are doing

A loop over the 26 letters draws each key: a light box from keyRect(i) with its letter centered on it.

```js
function draw() {
  // ...

  for (let i = 0; i < LETTERS.length; i++) {
    const letter = LETTERS[i]
    const k = keyRect(i)
    ctx.fillStyle = '#e7e5e4'
    ctx.fillRect(k.x, k.y, KEY_W, KEY_H)
    ctx.fillStyle = '#1f2937'
    ctx.font = 'bold 18px sans-serif'
    ctx.fillText(letter, k.x + KEY_W / 2, k.y + 24)
  }
}
```

What it means

• The loop runs for i = 0 to 25; LETTERS[i] is the i-th letter.
• k is the key's corner. The box is KEY_W × KEY_H there.
• The letter is centered (textAlign is still 'center') at the middle of the key, 24 pixels down.

Your turn

In draw, at the very end (under the end-message block, above the closing }), leave an empty line and write the loop. Press Run.
