How did you came up with this?
Did you use a source-to-source compiler or something like LISP?

Syntax error when running the tests cases --also sample tests-- in Chrome and Firefox.
Here is the stack trace:

Nice Kata.
I think there might be inconsitency between the basic tests and the random tests in Javascript.
The basic tests expect the solution to be

S(0) + S(1) + ... S(n+1).

while the random tests expects the solution to be

S(0) + S(1) + .... S(n).

for example, the basic test expect ƒ(5) to be 80, while the random test for the same number expects 48.
