Help with returning early patterns for functions

Tell us what’s happening:

I’m not really sure where to begin with this one! I do know that at the bottom of the function, I need to put “return undefined;”. Any help would be appreciated. Thank you!

Your code so far

// Setup
function abTest(a, b) {
  // Only change code below this line
  // Only change code above this line

  return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2));

// Change values below to test your code

Link to the challenge:

Test if either of the two parameters (a,b) is less than 0 if they are, return undefined.

if a condition || b condition

BTW, the default return values for all functions is undefined. So if you just return out of a function, by default it will return undefined.

Oh ok, I got it now. I appreciate your help. I guess I made it harder than it was supposed to be. Thanks again!!
