"Network Information API" (specification)

The Network Information API is a web technology that allows websites to access information about the user's internet connection. This includes details like whether the device is connected via Wi-Fi or cellular, the connection's effective bandwidth, and whether the connection is stable or metered (limited data). This information helps developers optimize website performance and user experience based on the quality of the user's network. Essentially, it enables websites to adapt their content to better suit the user's connectivity, enhancing browsing efficiency and satisfaction.
