A unique identifier for this Touch object.
A unique identifier for this Touch object. A given touch (say, by a finger) will have the same identifier for the duration of its movement around the surface. This lets you ensure that you're tracking the same touch all the time. Read only.

The Element on which the touch point started when it was first placed on the surface, even if the touch point has since moved outside the interactive area of that element or even been removed from the document.
The Element on which the touch point started when it was first placed on the surface, even if the touch point has since moved outside the interactive area of that element or even been removed from the document. Note that if the target is removed from the document, events will still be targeted at it, and hence won't necessarily bubble up to the window or document anymore. If there's any risk of an element being removed while it is being touched, best practice is to attach the touch listeners directly to the target. Read only.

A Touch object represents a single point of contact between the user and a touch-sensitive interface device (which may be, for example, a touchscreen or a trackpad).
Note: Many of these values are hardware-dependent; for example, if the device doesn't have a way to detect the amount of pressure placed on the surface, the force value will always be 1.0. This may also be the case for radiusX and radiusY; if the hardware reports only a single point, these values will be 1.
