The question is confusing and i'm not sure exactly how to work it out

not exactly sure what to do here and every result is wrong.

script.js 
function max( upper , lower){
var high = upper>lower
var low  = lower>upper
if (high == 15){

    }
}
console.log(max(15 , 5))

You need to use a conditional if statement to check which of the values passed in is largest.

function max(a, b) {
  if(a > b) {
    return a;
  } else if(b >= a) {
    return b;
  }
}

alert( max(2, 5) );

Perhaps these hints will help:

  • you won't need to create any new variables
  • don't look for any specific values inside the function
  • in your conditional ("if") test, be sure to compare the parameters against each other
  • when you determine one is larger, you must return that parameter
  • if the test fails, you must return the other parameter
  • you won't need an "else" or "else if"
