Tell me the output of the code below. Explain your answer?
Answer:
var lorem = { ipsum : 1};
var output = (function(){
delete lorem.ipsum;
return lorem.ipsum;
})();
console.log(output);
The output would be undefined, because the delete operator removed the property “ipsum” from the object “lorem” before the object was returned. When you reference a deleted property, the result is undefined.
