Need HELP !!!

Create a new function named max which accepts two numbers as arguments (you can name the arguments, whatever you would like). The function should return the larger of the two numbers.

HINT: You'll need to use a conditional statement to test the 2 parameters to see which is the larger of the two.

Can`t really understand !!!!

script.js 
function max () {

}

Hello!

The function helps you check which of the two numbers is larger. Therefore, the function needs to know which two numbers to check. You need to allow the function to have two parameters. It currently doesn't have any. It would look like this:

function max(firstNumber, secondNumber) {

}

But it doesn't do anything yet.

You have to check which number of the two (firstNumber and secondNumber) is larger. How could we achieve that? Yeah, that's right! With a conditional statement. 

function max(firstNumber, secondNumber) {
    if (firstNumber > secondNumber) { // we check if the first parameter is larger than the second one
        return firstNumber; // if it is, then we know which of the two is the maximum number
    } else { // it means that the first statement is false (firstNumber is NOT larger than secondNumber)
        return secondNumber; // then secondNumber is larger than firstNumber, so we return it
    }
}

Hope it helped!

The directions state to create two numbers for the argument, but only accepts words. Pure numbers do not work... Why is this?

There are two things you need to do.

  1. You need to do is give the function 2 parameters ie.(num1, num2)
  2. You need to make an if statement to test which is the larger number I hope this helps, Reply if you still need help. Khaleel
