+## Repeat method for Strings
+
+You could also create a method for this in String prototype. It is as simple as that:
+
+{% highlight coffeescript %}
+# add repeat method for all strings, that returns string repeated n times
+String::repeat = (n) -> Array(n+1).join(this)

 ## Discussion
 
 JavaScript lacks a string repeat function, as does CoffeeScript. List comprehensions and maps can be pressed into service here, but in the case of a simple string repeat it's easier to simply build an array of n+1 nulls and then glue them together.
