JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Using Array Methods

I'm stuck on this challenge please help?

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.

This is what I came up with, also has been tested in the console

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

This is what I see in the console which is what is being asked for

January, February, March, April, May, June, July, August, September, October, November, December

When submitted I receive this message

Bummer: There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'months.join(", ")')

Can anyone so me where I went astray in my code please the assistance would be much appreciated

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

You are declaring a variable that already exists, the simplest way to complete this challenge is:

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

But you could also add in an intermediate step if it's easier for you to conceptualize:

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