A Service Worker is a ghostly JavaScript program lurking behind the scenes of your browser. It boasts offline survival while in practice imprisoning users in a cage called cache. It juggles network requests like a capricious sovereign, sometimes responding, sometimes ignoring at will. If it works correctly, no one notices; if it fails, the ritual of cache clearing commences en masse. It is the silent overlord of modern web applications, reigning in the shadows.
