Web APIs (navigator, geolocation, history)

What advantage does this Permissions API approach offer over directly calling geolocation methods?

navigator.permissions.query({name: 'geolocation'}).then(result => {
  if (result.state === 'granted') {
    startTracking();
  } else if (result.state === 'prompt') {
    showLocationBenefits();
  } else if (result.state === 'denied') {
    showEnableLocationInstructions();
  }
  
  result.addEventListener('change', () => {
    // Handle permission changes
    console.log('Geolocation permission state:', result.state);
  });
});

It provides faster access to location data
It bypasses user permission requirements
It allows checking permission status without triggering permission prompts
This Permissions API approach allows checking permission status without triggering prompts: 1) It enables developers to determine the current state of geolocation permissions (granted, denied, or prompt) without initiating a permission request, 2) This lets applications customize the user experience based on permission status before attempting to use location services, 3) It allows showing educational UI explaining location benefits when the status is 'prompt', 4) It enables providing helpful instructions when permissions are 'denied', 5) The change event listener allows reacting to permission changes in real-time without additional queries, 6) In contrast, directly calling getCurrentPosition() immediately triggers a permission prompt if the status is undetermined, 7) This approach follows progressive enhancement principles by adapting the experience to the current permission context, 8) It creates a more considerate user experience by explaining why location is needed before requesting permission.
It works in browsers that don't support geolocation
