JavaScript is a client-side scripting language. In web developments, this means that it is script which is interpreted and processed by the web browser.
JavaScript is known to be used to manipulate HTML objects and add interactivity or control the use of information on a web site.
Some such examples of this would be when an interface is developed that responds to the movement or clicks of the mouse, or when a window pops up to inform you that you have not filled out a form correctly.
