We'll also look at three touch events:

• The touchstart event, which occurs when a new finger has just started touching the screen.
• The touchend event, which occurs when a finger gets lifted off the screen.
• The touchmove event, which occurs whenever a touching finger is moved.

Whereas you receive mousemove events even if none of the mouse buttons are down, obviously you can't receive a touchmove event unless a finger is down.

The information you receive for a touch is also different. Instead of a single coordinate, you get an array of coordinates corresponding to all the fingers which are touching.

Let's get started with an example.
