months.join(", ");

console.log(months);

Use the array method that combines all of the items in an array into a single string. In the final string, the array items should be separated by a comma AND a space. Finally, log the final string value to the console.

Your code looks good in terms of joining the array items into a string. Now instead of logging months to the console (since the value of var months is still the array listed at the top), you should assign the new string to a different variable, then console log that new variable.
