code: function(el, attrName) {
                      var prop = attr.map[attrName];
                      if (typeof prop === "string" && el[prop]) {
                          return el[prop];
                      }
  
                      return el.getAttribute(attrName);
                  }
docs: ## attr.get Gets the value of an attribute. First checks to see if the property is a string on `attr.map` and if so returns the value from the element's property. Otherwise uses `getAttribute` to retrieve the value.
