Challenge: Understanding Undefined Value returned from a Function

Hi there,

you did not called two functions,

function addThree();
function adFive();

The challenge tells to return the value of the function addFive(); so you can try to understand this.
You can have a variable assigned to the function addFive(); to validate.

Let me know if you understand it, or solved the problem :slight_smile:

Ya,thank u very much

you can have the function like this

function addFive(){
sum += 5; // with no return 
};

or

function addFive(){
sum += 5; 
};
// add a variable to return and validate undefined.
addThree();
var valueReturned = addFive();
console.log(valueReturned); // output undefined.
