just review the markdown cheatsheet for code use

Code

Wrap your code with 3 backticks () on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting. html <p>This is code!</p> ```

Yeah the code is too much, but u know.. I tried with the knowledge I have. Im sure it will be much shorter when I learn how to loop and make usable functions.

Thanks Daniel.

Here the script you've provided. It's nice and messy because you did not use the next chapter of your learning js: loops and function. When you get learned about it the whole code become much shorter and "expressive". Wish you happy learning the next chapters of your js course, Ahmed!
