A function that draws

What we are doing

The picture will change with every letter you type, so it will be drawn again and again. We put the drawing lines in a function named draw; one call, draw(), repaints everything.

```js
function draw() {
  ctx.fillStyle = '#18181b'
  ctx.fillRect(0, 0, canvas.width, canvas.height)
}

draw()
```

What it means

• function draw() { ... } defines the recipe; it does not run yet.
• The lines between { and } are its body, indented by two spaces.
• draw() with parentheses runs it.

Your turn

Wrap the two drawing lines in function draw() { ... } (indented by two spaces) and call draw() after it.
