The getRegistrations() method of the ServiceWorkerContainer interface returns all ServiceWorkerRegistrations associated with a ServiceWorkerContainer in an array. If the method can't return ServiceWorkerRegistrations, it returns a Promise.
ServiceWorkerContainer.getRegistrations().then(function(ServiceWorkerRegistrations) { ... }); None.
A Promise that resolves to an array of ServiceWorkerRegistration objects.
navigator.serviceWorker.getRegistrations().then(function(registrations) {
document.querySelector('#status').textContent = 'ServiceWorkerRegistrations found.';
