The Network Information API
The Network Information API provides information about the system's
connection in terms of general connection type (e.g.,
‘wifi’, ‘cellular’, etc.). This can be used to
select high definition content or low definition content based on the
user's connection. The entire API consists of the addition of the
NetworkInformation interface and a single property to the Navigator
interface: Navigator.connection.
Note: This feature is available in Web Workers.
Example

Why do we use it?
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
