Bummer! You must pass a string with a comma AND a space -- ', ' -- as the argument to the .join() method.

script.js
var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];
var arrayString = months.join(' , ');
console.log(arrayString);

Please explain what problem/error you're getting (what is happening and what you are expecting to happen). Your JavaScript code runs just fine for me.

I believe they are wanting the months printed out with a comma and a space. Your code is correct except for one extra space before the comma in your .join(). It should look like this:

var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];
var arrayString = months.join(', ');
console.log(arrayString);

But still its not working.

I can confirm that this indeed results in a correct answer in the code challenge. SuneethaRani, please double check your code.
