Answer 1

Answer:

The advantages of using JavaScript are:

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.

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.
