jQuery generally abuses (or takes advantage of, depending on your perspective) the value of "this" in its callback functions, in places where it would really be better to have an explicit argument. For example:

    AccountView.prototype.render = function() {
      $(".account").click(function(e) {
        // `this` is now the same as `e.currentTarget`
        // But `e.target` is also useful.
        // And you what you really want is for `this`
        // to still point at the AccountView instance.
      });
    };
