A service worker is a script that your web browser runs in the background, independently of a web page, and does not require user interaction.

Service Workers are useful because they make it possible for websites and web apps to load their content more quickly, irrespective of the network that is being utilized. They make it possible with the help of offline access, push notifications, background sync, and many other additional capabilities coming with Service Worker.

Service employees are responsible for the storage of objects that have been brought back from visited sites and retained locally for a variety of reasons. This ensures that loading is done as quickly as possible. Items may be stylesheets, scripts, HTML, photos, or any one of a wide variety of other assets.

Service Worker Cache is a form of cache used by Chromium-based browsers to store static page contents such as images, scripts, stylesheets, and other resources for faster loading and offline access.
