WakeLockSentinel: type property

A string representation of the currently acquired wake lock type. The type 'screen'` is a screen wake lock. It prevents devices from dimming or locking the screen.

This example shows an asynchronous function that acquires a WakeLockSentinel, then logs the type to the console.

const requestWakeLock = async () => {
  wakeLock = await navigator.wakeLock.request("screen");
  console.log(wakeLock.type); // logs 'screen'
};

requestWakeLock();
