I know this might sound stupid, but when do you use JavaScript?

Question

Help

Answer 1

JavaScript adds behaviour and dynamic functions to a webpage. This can be done in many different ways depending on what needs to be done.
The user can interact with the page without reloading and sending its content to the server.
Some examples could be:
Form evaluation, alerting and prompting user to enter info, calculations, animation (now with CSS3), canvas drawing (games), shopping cart interaction and many more..
