random text on login/refresh

Ok this is probably a really dumb question but anyway (I'm still learning...) - notice on the Major Geeks homepage, everytime you enter the site or refresh the page it shows a different slogan on the top?

Will someone please care to explain to me how this works - like what is this function called and what code is probably being used here and the principle behind it? I'm not asking for the code - that I can figure out eventually but please at least point me in the right direction here?

 

you have a bunch of quotes. say 10.
You make an array and add the quotes (as a string) to the array.
arrays are indexed 0 to n

so you make a function that randomly accesses an index of the array and writes it out to the browser.

 

Hi Kodo

Thanks - you make it sound so easy although I'll probably spend hours making it work anyway - but at least now I know where to start...
