Basic JavaScript - Return Early Pattern for Functions

JavaScript

Tell us what’s happening:
Describe your issue in detail here.
There’s nothing really an issue yet, I have been going through JavaScript and I was wondering if this is a situation that you could also use a switch statement instead of the “if” statement. If so, what would it look like for this situation? Thank you in advance.

Your code so far

// Setup
function abTest(a, b) {
  // Only change code below this line
if (a < 0 || b < 0)
 return undefined;


  // Only change code above this line

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

abTest(2,2);

A switch isn’t exactly a replacement for an if statement, but yeah, you can put return statements inside of switch cases.

Note: If your if is on multiple lines, its best to use {}s for clarity

  if (a < 0 || b < 0) {
    return undefined;
  }

Yes, you could. I would say that almost no one would, but it is possible.

I think you should play around and try to figure it out on your own. Just giving you the answer would take all of the fun out of it for you :slight_smile:
