+## Problem
+
+You want to create a string from an array.
+
+## Solution
+
+Use JavaScript's Array toString() method:
+
+{% highlight coffeescript %}
+["one", "two", "three"].toString()
+# => 'three,two,one'
+{% endhighlight %}
+
+## Discussion
+
+`toString()` is a standard JavaScript method. Don't forget the parentheses.
