i've done it everyway possible. it still won't work.

i've tried with a space and a comma. before and after. i've tried it with just a space before the comma. nothing is working.

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

Hi Kim Dallas

You're close. Everything is syntactically correct, but if you have a look at the error message the Code Checker is giving, it will tell you exactly what is wrong:

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

You are passing a space AND a comma AND a space. If you delete that first space the task will pass.

Nice work! :) :dizzy:

i've tried that Jason. I tried var monthsString = months.join (' ,'); console.log (monthsString); and it still won't work. it's driving me nuts. it's like it's stuck no matter what I do.

In your comment, you now have space and comma instead of comma and space.

The code does pass if you take the original code above and just delete the first space there:

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

thank you. Jason. so the space has to be behind the comma.
