Web APIs (navigator, geolocation, history)

What Navigator property and related events does this code utilize?

if (navigator.onLine) {
  syncData();
} else {
  storeDataLocally();
}

window.addEventListener('online', () => {
  syncData();
});

window.addEventListener('offline', () => {
  showOfflineNotification();
});

navigator.connection and connection events
navigator.network and network events
navigator.onLine and online/offline events
This code utilizes the navigator.onLine property and online/offline events: 1) navigator.onLine is a boolean property that indicates whether the browser currently has network access, 2) The code checks this property to determine whether to sync data or store it locally based on connection status, 3) It adds event listeners for the 'online' event, which fires when the browser regains network connectivity, 4) It also listens for the 'offline' event, which triggers when network connectivity is lost, 5) These events are attached to the window object, not the navigator object, which is a common source of confusion, 6) This pattern implements the offline-first approach, providing resilience against network interruptions, 7) It's important to note that navigator.onLine may not always accurately reflect actual connectivity to specific servers, only general network availability, 8) This approach enables creating progressive web applications that continue functioning during temporary connectivity loss.
