mary has a reference to
john. to remove the circular reference, either remove or unset the property
brother from the
mary object or the
sister property from the
var john = new Object(); var mary = new Object(); john.sister = mary; mary.brother = john; // This line causes a runtime error. var error = JSON.stringify(john);
