i would the best thing to do regardless of your selection method is to store
them in variables.
like this
var obj = $(".wrap");
Now you have basically created an object reference point. you won't need to
re-create in 99% of cases.
so lets re-use our object reference.
// get the width of your object without making a new reference
var obj_width = obj.width();
// get a child element in your object without making a new reference to your
object
// also you are only searching within your object, not the whole page.
performance boost here
var element_in_object = $(".elementclass", obj);
//if you only need to make one reference in your whole script theres no need
to make so //many vars.
//you can point directly to it
// this would be more efficient if you don't need to reference your "wrap"
class again
var my_element = $(".wrap .elementclass");
I already know theres gonna be people ready to debate on their methods :)
but this is my thoughts.
