Controls allow us to interact with our map. They also allow us to display extra information, such as displaying a scale bar with the ol.control.ScaleLine
control. Before, in the previous generation of OpenLayers, version 2.x, some controls did not have a visual appearance. Nowadays, those elements, which do not rely on a DOM element, are called interactions like for example, touch interactions on mobiles. You can have as many controls on your map as you'd like. There are even some cases where you may not want any controls—such as embedding an unmovable map in a page, or showing a static map for printing.
