Draw one wall

What we are doing

The walls of the table are straight lines. We draw the first one: the left wall, from (20, 470) up to (20, 120).

```js
ctx.strokeStyle = '#a8a29e'
ctx.lineWidth = 4
ctx.lineCap = 'round'
ctx.beginPath()
ctx.moveTo(20, 470)
ctx.lineTo(20, 120)
ctx.stroke()
```

What it means

• strokeStyle is the line color, lineWidth its thickness, lineCap = 'round' rounds its ends.
• beginPath() starts a new shape, moveTo puts the pen down, lineTo draws to a point, stroke() paints the line.

Your turn

Write the seven lines at the very end, under the fillRect line, then press Run.
