Lua translation!

n + 2 is outside the range. if n was 12, then yes, the 11-13 pair should be counted.

Well, if it's end-inclusive then for input 11 shouldn't it result in 3 instead of 2 since 11 + 2 is also prime?

Anyway, the description is still unclear imo.

How does this match with "If n is wrapped by twin primes (n-1 == prime && n+1 == prime) then that should also count even though n+1 is outside the range." ? That sounds end-inclusive ( and even slightly overinclusive, but specified unambiguously nevertheless ).

Fixed. JS tests now use identical parameters to Python.

Your mission, should you choose to accept it, is to write a function that counts the number of sets of twin primes from 1 to n.

It was not mentioned that the range is end-exclusive.

that should have fixed the issue then

the tests are missing require 'prime' (which is a standard Ruby module) at the top (they currently rely on the fact that the author's solution does require it)

fixed here

In Ruby, I seem to have to create an alias for my function called Prime before the random tests will run.

fixed in OP's fork

Approved

python new test framework is required. updated in this fork

Python :

• The example tests aren't using the test framework, and both test suite and example tests are missing the imports (user's solution + framework).

Javascript reference solution is too slow to use the same range. Maybe it should be rewritten.

Yes. I solved that kata. I looked my old solution and I solved this kata. I forgetted How can I use fastly prime number calculate method. I remember again. Thank you man. Respect.
