{{APIRef("Sensor API")}}{{SeeCompatTable}}

The x read-only property of the {{domxref("Accelerometer")}} interface returns a number specifying the acceleration of the device along its x-axis.

Value

A {{jsxref('Number')}}.

Examples

Acceleration is typically read in the {{domxref('Sensor.reading_event', 'reading')}} event callback. In the example below this occurs sixty times a second.

const accelerometer = new Accelerometer({ frequency: 60 });

accelerometer.addEventListener("reading", (e) => {
  console.log(`Acceleration along the X-axis ${accelerometer.x}`);
  console.log(`Acceleration along the Y-axis ${accelerometer.y}`);
  console.log(`Acceleration along the Z-axis ${accelerometer.z}`);
});
accelerometer.start();
