Workshop › Angry Birds-style Slingshot › Step 7 of 47
A dark line from the top of the sling to the bird is the rubber band. It is drawn before the bird, so the bird sits on top of it.
```js
ctx.strokeStyle = '#451a03'
ctx.lineWidth = 3
ctx.beginPath()
ctx.moveTo(SLING.x, SLING.y)
ctx.lineTo(bx, by)
ctx.stroke()
```strokeStyle and lineWidth are the line's color and thickness.moveTo puts the pen down at the sling without drawing; lineTo draws a straight line to the bird.stroke() paints the line (while fill() paints the inside of a shape).In draw, write the six lines between const by = ... and ctx.fillStyle = MATERIALS.bird.color.
