An array has a method to glue all elements together, Array.join. Without an argument, it would use a comma (,) as glue. To put every element on a new line, use the newline character (n).

var your_array = [ Alice, Bob, Eve ];

var textarea = document.getElementById(your_textarea);

textarea.value = your_array.join(n);

<textarea id=your_textarea></textarea>
