I have this code:
var prop = $ ('body);
Does the 'prop' allocate more memory space or is it just referencing the element?

1Depends on what the `$` function does.. Is it jquery?. – Keith Jan 05 '18 at 16:08

function $(key){ return document.getElementById(key); } – Thiago Feijó Jan 05 '18 at 17:12

Then prop is just a reference to a DOM node.. – Keith Jan 05 '18 at 17:24

Is there any documentation or any place that says this? would be very useful to me. – Thiago Feijó Jan 05 '18 at 18:29

"prop" in your example is just a reference object. It only occupies space to store information like location of element in the DOM, element properties and inherited functions.
