Hi there,

I'm not sure if I can fully answer your question but I can offer a bit of information on why your code returns "10" instead of "3".

Take a look at "parameters" under the toString() method documentation. Passing a number to toString() sets the radix for the conversion, determining the base of the number system that will be used.

Referring to the code inside your alert:
string.length.toString(string.length)
Since the length of the string "Joe" is 3 you can rephrase this as "convert the number 3 to a string in base 3 (ternary)". In ternary the number 3 is represented as 10.
