A message line

What we are doing

A message above the sea tells the player what is going on. It lives in a variable, so any part of the game can change it.

```js
let message

  message = 'Your turn: pick a square'

  ctx.fillStyle = 'white'
  ctx.font = 'bold 16px sans-serif'
  ctx.textAlign = 'left'
  ctx.fillText(message, SEA.x, 34)
```

What it means

• message is set in reset and drawn every frame above the enemy's sea.
• textAlign = 'left' makes the point the left end of the text.

Your turn

1. Under let myShots ... write let message.
2. In reset, under myShots = grid(null), write the message line.
3. In draw, above drawSea(SEA, BIG, myShots), write the four text lines.
