The main advantage to JavaScript validation is that it allows for instantaneous feedback for the user. User's are less likely to become annoyed if the form is capable of telling them that their data is invalid right away.
Client-side validation also leads to less traffic. Rather than the server having to receive the entire HTML form POST, just to have it return an error, you can instead significantly cut down on the amount of data being sent to and from the server.
It's important to note that even with JavaScript validation, server-side validation in a higher language must be done. JavaScript is client side, so it's possible to circumvent JavaScript validation with very little effort. If you rely solely on JavaScript validation, you will eventually receive bad (even potentially harmful) POSTS at the server. A web developer that doesn't do server-side checks has a very short career.

How does javascript validate input?
Since JavaScript is a client-side language, all input will be validated on the client-side. This could be simple validation of forms such as checking if the user-submitted e-mail is actually an email, or if the submitted name doesn't have special characters (!#%) etc. These validations can easily be bypassed by manipulating the javascript, so it's not safe. Typically you would do some validation on the server-side just to be safe when storing to a database.
