<p>I am curious, within the same function, when <code>$(this)</code> is called multiple times does it incur additional overhead for constructing the jQuery object in the subsequent calls? In other words, is <code>$(this)</code> cached the first time it's called? If not, would it be a better practice to store <code>$(this)</code> in a variable and use that variable when <code>$(this)</code> is needed subsequently?</p>
