When adding if condition to the code, I got confused...Can anyone help a little bit?

The questions are below.

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.

script.js 
function max (10,20){
  if (10<20){
    return 20;
  }
}

No worries, you don't always need an else condition though. :)

Just ran the challenge with a pass

function max(a,b) {
  if (a < b) {
    return b;
  }
}

alert(max(5,7));

When you assign integers as arguments, you are "hard coding" that argument.

You want to get away from that black/white programming concept and think of fluidity and re-usable code.

function max(a,b) {
  if (a < b) {
    return(a);
  }
}

In this example, I have left the arguments to be whatever the input from user is. As (a) becomes a variable, and the data that get's "passed" into that argument is stored by (a). The same is with (b).

The return method is your choice. There are many different statements to execute from an if/else statement.

The fluidity comes from the function call...

max(3,8);

What if you want to change the value returned from max throughout your program as a dynamic integer?

if you call YOUR function max(10,20); the result will always be the same, but when we assign arguments to store the data, the process becomes very fluid.

function max (a,b) {
  if (a < b) {
    return b;
  }
}

The challenge asks that you return the larger of the two, and no parenthesis around the value result of your return.

Another student just told me that I was missing an " else" condition, and once I added it, it worked. Again, thanks for helping.
