PointerEvent: pressure property

The normalized pressure of the pointer input in the range of 0 to 1, inclusive, where 0 and 1 represent the minimum and maximum pressure the hardware is capable of detecting, respectively. For hardware that does not support pressure, such as a mouse, the value is 0.5 when the pointer is active buttons state and 0 otherwise.

In this snippet, when a pointerdown event is fired, different functions are called depending on the value of the event's pressure property.

someElement.addEventListener(
  "pointerdown",
  (event) => {
    if (event.pressure === 0) {
      // No pressure
      process_no_pressure(event);
    } else if (event.pressure === 1) {
      // Maximum pressure
      process_max_pressure(event);
    } else {
      // Default
      process_pressure(event);
    }
  },
  false
);
