What do you mean by "Service Workers" in the DevTools?

Service Workers are a web technology that enables the creation of scripts that run in the background of a web page or web application.
They can intercept network requests, cache data, and serve cached content when the network is unavailable or slow.
In the DevTools, you can view and manage service workers in the “Application” tab.
The “Service Workers” panel displays information about the active service worker, including its status, scope, and cache storage.
You can unregister or update the service worker from this panel.
Service workers can be used to create offline-first web applications, improve website performance, and provide a seamless user experience.
They are supported by most modern web browsers, including Chrome, Firefox, Safari, and Edge.
