Hi Ashok,

You are very close. In your 'join()' method, you need to pass the separator you wish to use and the array you are wanting to use it on. In this case, you want a comma (with a space) to separate the array of months. So, your code will look like this:

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

Hope that makes sense and clears it up for you. :) Jason
