Fixed.

Hello, please, fix the example with 6 = 6, 36, 45, 41, 17, 50, 25, 29, 85, 89, 145, 42, 20, 4, 16, 37, 52, 29. 37 = 3^2 + 7^2 = 9+49 = 58, not 52

I don't think so, could you give more detailed information about what you think is wrong?

some bugs in js version?

Done.

Could someone approve this translation? It uses the same algo as performance kata so it should be working correctly.

Hi, @TySlothrop, I've created a performance version of your kata. Would you mind adding a link to it in your description? :)

The one you mentioned - return true if n is happy.
This one - return all numbers in range [1..n] which are happy.

Is this any different from this kata, which already has JS and python support? (among other languages)

There's no performance requirement though so it's not ranked too low.

Python translation available! Please review and approve it ;)

NOTE: lowered maximum random number from 10000 to 5000 because naive solutions may not be able to pass tests with numbers in range 2-10000.

Agreed! At least a 5kyu. Uff....

The O2 safe level chart is already preloaded. Why reinventing the wheel? ;-)

Great kata! Perhaps a typo in the desciption? Should step seven read 1 ^ 2 + 3 ^ 2 + 3 ^ 0 = 10
instead of 1 ^ 2 + 3 ^ 2 + 3 ^ 2 = 10?
