HERE Maps API supported web browser (basically any modern browser should do).
Example code
This example will start panning the map to the right, then after a moment changes direction to the left and continues forever(?) ;) Unless you stop it by pressing the button and clearing the timer and interval settings. Remember to add in your own AppId and Token to get it to work.

Summary
Using the map panning feature you could create e.g. a game, where the map is moving and the user should e.g. find something on the map and click it before the area vanishes from sight, just an idea ;) develop your own =)? Side scrolling game...? =)
