The $paras declaration identifies it as a jQuery object. The "$" doesn't
hold any special function, it's just a way of using Hungarian Notation.
Take the following:
var el = document.getElementById("products");
var $el = $(el);
You now you know that "el" is a reference to the straight DOM object, while
$el is a reference to the jQuery equivalent.
