I believe it wasn't Liam's replacement logic that ran him aground, 
but rather the fact that he was probably passing his function a 
Number object to which he was attempting to apply a String object 
method.  Once that argument is converted to a string, I believe 
replace() would work, either using RegExp as you suggest or a string 
as Liam was doing.
