I've written my first JavaScript. Now I want to use one of those free web hosting sites. Is it as simple as uploading my script and giving out the url they give me?

If if helps to know, there will be no data stored on the server, it's just a simple script I want the server to send to people. The script itself uses HTML5 localStorage so I'd think that might make things more simple. What are we talking here?

Will my situation be easy or are we talking rocket science here?
