The Range.detach() method releases a Range from use. This lets the browser choose to release resources associated with this Range. Subsequent attempts to use the detached range will result in a DOMException being thrown with an error code of INVALID_STATE_ERR.
range.detach();
var range = document.createRange();
range.selectNode(document.getElementsByTagName("div").item(0));
range.detach();
