How do I do this?

Beneath the max function you just created, call it with two numbers and display the results in an alert dialog. Pass the result of the function to the alert method.

For example, to display the results of the Math.random() method in an alert dialog you could type this:

alert( Math.random( ) ); How do I answer it

script.js 
function max(n1, n2) {
if (n1 > n2) {
return n1;
} else {
return n2;
}
}
alert( Math.random(n1, n2 ) );

Hi there! You made a function named max and you're supposed to call it and give it two numbers. But instead, you're calling a Math.random function and sending in two undefined variables. Remember, n1 and n2 are undefined outside of the function. To call a function we simply give the name and then any arguments in parentheses. So the line you're missing is:

alert(max(100, 150));

This will call the max function and send in 100 which will be assigned to n1 and 150 which will be assigned to n2. Because the else statement will be executed, the value of n2 will be returned to the alert. This means that 150 will be printed out in the alert that pops up. Note that you could substitute the 100 and the 150 for any numbers of your choosing.

Hope this helps! :sparkles:

That 'Math.random()' was just an example, in your alert method you need to call the function you just created with two numbers as argument. Those numbers can be any numbers you want. Your alert method should look something like this:

alert(max(4, 12));
