A lot of my pages have amll bits of jquery.

Im thinking of putting them into one external file with one `$(document).ready(function() {`

and everything in there.

is this a good/bad idea?

will each page be slower overall if there is more code to execute even if its not relevant to the page? i imagine each line of code in the external script gets executed when the **dom** is ready..? or is my understanding wrong?
