Create a new function named max() which accepts two numbers as arguments

Hi,

This seems like it should be simple.

What am I missing? Thanks-

script.js 
function max(3, 4){
  if(4 > 3){
    return 4;
  } else {
    return 3;
  }

}

Hi Juliette,

It's a little more involved than that. What you want to do first is set up parameters for your function which are kinda like placeholder variables. So it would look more like this..

function max($one, $two){

}

Those are what are known as parameters. 

function max($one, $two){
  if($one > $two){
    return $one;
  } else {
    return $two;
  }

}

the rest of your function is fine. You just need to replace the numbers with the parameters (or the variables) But how does JS know which number is higher than the other? The numbers are passed in at function call.

max(4,3);

Those are your function arguments. :-)
