Question

Here's the question:

Inside the function, return the sum of the num parameter and 10.

Bummer: The 'add10' function needs to return the sum of the 'num' parameter and the number 10.

My answer:

function add10(num) {
 return num = 10;
  }
console.log(add10);

I keep getting an error. Any pointers? If you will be so kind as to explain your answer and what I did wrong I will be doubly appreciative.

Thanks in advance,

Shari

You need to invoke/call the function add10() and pass a number. However, the function will return 10 each time.

What you can do is return num + 10 and that will return any number you pass in, adding 10 to it.

function add10(num) {
      return  num  +  10;
  }
console.log(add10(100)); // returns 110
