What does this number mean when I run this line in console?

Hi,

I ran this random line in console in FF and it returned the number 14:

setTimeout(function() { $(‘.footer’).fadeIn(1900); },2100); 14

setTimeout(function() {
            $('.footer').fadeIn(1900);
         },2100);  

What does the number 14 reference?

Thanks

that is the “process id” of the timeout callback, if you want to cancel it ( via clearTimeout() ) before it runs.
