What is a good definition of Client Side vs. Server Side Javascript Programming?

Thanks

Server Side - generates some data, which may or may not be HTMLish, which is sent one way to client. (Or even more abstract, out an output stream to wherever).

Client Side - runs within the client's user agent (web browser), doesn't have anything to do with the server- ie: javascript embedding in an html file doesn't really care if the file came from a web server or was read off a hard drive.

Thanks,

That was what I thought but had to verified it.
