Hey Melvin,

the join method returns all the array items separated by the specified separator, however it's not overwriting the existing variable (in this case months), so you're logging the array to the console.

Just save the result of the join method on the months array to a new variable and log it out to the console and you should be good to go! :)

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


var finalString = months.join(', ');
console.log(finalString);

or you could also directly log the return value of the join method to the console like so if you prefer:

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

console.log(months.join(', '));

Thanks I figured it out already, prior to you answer. Thanks a though!

Here's how I did it. Here's another way var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];

months.join(); console.log(months.join(', '));

Glad you got it working! :) Yep, perfectly fine as well. But you didn't even have to write the first months.join(); as it won't be evaluated. Also note that if you use the join method without any arguments it will separate all items in the array with a "," but it won't put a space after the comma like the challenge requires. Happy coding!
