what am i doing wrong?

does the join method need to be inside the if statement?

script.js 
var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];
var singleString = months.join(', ');
  for (i =0; i<months.length; i++){
    console.log(singleString[i]);
  }

Hello, you're doing great. You don't need the for loop though; the join function is enough on its own (does all the heavy lifting for you).

   var singleString = months.join(', ');
   // then log the singleString to the console

In fact, you really don't have to save the string in a new variable. For instance you could do

   console.log(months.join(', ')); // log the new string directly to the console

You don't have an if statement anywhere.

Also, the challenge is asking for you to just use the .join() function.

It doesn't make sense to use a loop on singlestring since the .join() function returns a string, so it doesn't have any index to iterate. The .join() function does the looping for you to put the comma space between each array element.
