Help with the array.join() challenge

Hi,

I've tried to solve the challenge but it isn't giving me a good answer but when I use the same code in the console its working. Am I missing something?

script.js 
var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];
months.join(", ");
console.log(months.pop());
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">

<body>
<script src="script.js"></script>

Why do you use .pop() inside the console log !? You should use this method only if you want to remove an element at the end of you array.

To pass this challenge you could do this:

var months = ['January','February','March','April','May','June','July','August','September','October','November',
              'December'];

var final_string = months.join(", ");
console.log(final_string);
