The question asks you to compare two numbers using two arguments. When I hear "compare," I think conditional. So "if, else" statements. We are creating a function with two arguments and then we will pass in two numbers to compare:

function max (num1, num2) { //function name with two parameters, num1 and num2
  if (num1 > num2) { //comparing if num1 is greater than num2
  return num1; //if num1 is greater than num2, return that value
  } else { //if num1 is less than num2, return that value
  return num2;
  }
}
alert(max (3, 4)); //passing in 3, and 4 as num1, num2 and alerting the answer.

Good luck! Let me know if you need more explanation.

Hey, Leslie!

To get proper syntax highlighting, add the language you intend it to be after the three backticks (in this case ```js). Already edited for you here, but keep in mind for future use!

Cheers!
