There a .length property to see how many elements a jQuery object references, so just combine that with a .class selector, like this:

var count = $(".goo").length;

var amountOfGoo = $('.goo').length;

Maybe $(".goo").length

You can use the .length property. So something like var total = $('.goo').length; should do the trick.

$(".goo").length
