What will be the output of the code below? var abc = { x: 10 }; var result = ( function () { delete abc.x; return abc.x; })(); alert(result); Answers:- The output would be “undefined”. The delete operator is used to delete the property of an object. Here “abc” is an object which has the property “x”. It's a “self-invoking” function and we will delete the x property from object “abc”. When you try to return a deleted property, it will return “undefined”.
