Javascript Arrays

I am having trouble with using the .join method for adding to arrays.

You use the join method on arrays. For example..

var studentNames = ['Alex', 'Joe', 'Carter'];
var allStudents = studentNames.join(", ");

Then when you print allStudents it would look like this Alex, Joe, Carter

Can you give an example of your code? Be sure not to forget the parentheses .join();

Mr. Treadway,

Here is an example of my code.

var welcome = correctGuess.join(' ,'); document.write("You got " + welcome + " questions correct"); document.write("You got " + incorrectGuess + " questions incorrect");
