Maybe in the case of logging or where the web page is constantly showing new data. An example I can think is a web based interface for controlling a drone. This could be used on the page to store the timestamped output of various sensors. It would allow for the data to be displayed while also maintaining a history of the data in the browser. Could add in filters and searches as well as a pause functionality to review the historical data. Sort of like a dmesg for the web page. I'm thinking practical uses are sensor monitoring and server monitoring.
