Try an "attempt", the "test" is failing for me as well.
I believe the logic in test and attempt is different.

How did you get this to work without getters? I copy and pasted your solution and it didn't work because the methods that were being called didn't exist.

this was Python 2

I must have broken something when updating this kata to Node 18. Should be fixed now, please veryfy (you might have to click RESET to see new tests, so make sure to back up your solution).

I get this error in JavaScript, even when all my function does is console.log() or return 0.

ReferenceError: Test is not defined
    at Context.<anonymous> (test.js:9:1)
    at process.processImmediate (node:internal/timers:471:21)

This would return False for 4.0, but that should be True based on the constraints in the description (only floats with a decimal part not equal to 0 are uneven).

I wanted to do it recursively but I couldn't figure out how to keep track of the counts, of course now it seems so obvious, you just add once each time the function is called!

this is how I did it at first then I realized I could use a Counter.

nice use of or

the problem also states that human_years >= 1 though

AAAAAAAAAAAAAARRRRRRRRRRRRGGGGGGGGGGHHHHHHHHHHHHHHHHH

it creates a dictionary where the keys are the characters in s and the values are the number of times they occur in s.
