JavaScript JavaScript Basics (Retired) Creating Reusable Code with Functions Create a max() Function

Posted by Darren Head

Create a new function which accepts two numbers as arguments, use conditions to test to see which number is larger

Hi All,

I am having problems with this question. I have tested with my own code in the console and with an alert box and it does return the higher value, however it keeps saying I'm incorrect:

  • "Bummer! The max() function doesn't seem to work. It should return the larger of the two numbers." *

Please take a look at my code below, not the prettiest but does return my higher value of 10.

function max(low, high) {
  var low = 1;
  var high = 10;
    if (low < high) {
      return high;
    } else {
      return low;
    }
}

console.log(max());
alert(max());

All help appreciated, Thanks!

Darren;

Pull your variable declarations out of your function, and when you call the function add them as arguments and it will work just fine.

Thanks Ken, works great now - I knew it was something very simple.
