Inside the function you can call an if statement. So you could so something like this if I'm not mistaken:

function max(var1, var2) {
  if (var1 > var2) {
    return var1:
  } else {
    return var2;
  }
}

I'm not much of an expert on JS as I'm still learning but I think this should work.

The question seems to be asking us to "Create a new function named max which accepts two numbers as arguments". Good job on naming the function (that part is works).

It seems where the question gets a bit confusing is the two numbers part. When you define the function you need to give the arguments names to be uses as parameters (they work like variables). You will give the function actual numbers later when you call it.

As for how to determine which is larger, there are many ways to do this, but, here, it hints to use " a conditional statement" for example an if ()... else statement. Then you can return the larger number based on the conditions that you test for.
