{{ APIRef("Pointer Events") }}
The twist read-only property of the
{{domxref("PointerEvent")}} interface represents the clockwise rotation of the pointer
(e.g., pen stylus) around its major axis, in degrees.
A long value representing the amount of twist, in degrees, applied to the
transducer (pointer). The value is in the range 0 to 359,
inclusive. For devices that do not report twist, the value is
0.
When a {{domxref("Element/pointerdown_event", "pointerdown")}} event is fired, different functions are called
depending on the value of the event's twist property.
someElement.addEventListener("pointerdown", (event) => {
if (event.twist === 0) {
// No twist
process_no_twist(event);
} else {
// Default
process_twist(event);
}
});
