How come my function does not return the higher number?

function max (x,y) {
  return large;
}
x = 10
y = 20
if (x>y) {
  large = x
}else if (x<y) {
  large = y
}

Hi Aviv,

Large is not defined here. So it has no idea what to do with it. If you wanted to make "large" a variable, you could do it like this:

var large;

This variable is emtpy, by the way. It doesn't hold anything.

But, in this case, there is no need for that. You can make a function that takes 2 parameters, we'll name them foo and bar. The function itself will check which one is the highest and returns it. If foo is higer than bar, it will return foo. If not, this means bar is always higer than foo and it will return bar. 

function max(foo ,bar) {
    if (foo > bar) {
        return foo;
    } else {
      return bar;
    }
}
