,JavaScript

Advantages of JavaScript:
Less server interaction − You can validate user input before
sending the page off to the server. This saves server traffic, which
means less load on your server.
Immediate feedback to the visitors− They don’t have to wait for a
page reload to see if they have forgotten to enter something.
Increased interactivity − You can create interfaces that react when
the user hovers over them with a mouse or activates them via the
keyboard.
Richer interfaces− You can use JavaScript to include such items as
drag-and-drop components and sliders to give a Rich Interface to your
site visitors.
