can you find a use?

I am new to javascript but i think i have managed some good scripts. I have created a number generator and a key generator (combination of numbers and letters)

These can be found at the following urls:

Then you have the number genrator:

Please tell me if you can find a use for these codes, also what do you think about them? remember i am new to javascript and found it hard going straigt from html to javascript without suing xhtml first.
