This solution of mine isn't consistent.

var code = [5,5,5];
function tryCode(indications) {
// TODO : indications are null or a 3-digits array.
if(indications){
indications.map(function(e,i){
code[i] += indications[i];
})
}
return code;
}

This is my refactored solution! Codewars is having problems with accepting another solution.

Your description needs work

0 = correct digit
-1 = higher digit
1 = lower digit

I have to interpret your example and not your instructions.
FIX IT PLZ

Preloaded as Fruits[];

return Fruits;

It isn't defined.
Fix this please.

Whats the point of lambdas in Ruby?

Haha nice!

Here's why I think you got it wrong

1. your parameter in the function is arr
2. the array in question is called questions

I don't believe the code kata inputs the questions array into any function.

I don't think you're wording the backstage conditions correctly or they are not very clear:

Here's what I understood from it at the beginning:
Backstage should increase in quality += 1 every sell in
If backstage sell ins are <=10
they should increase by 2 instead
If backstage sell in are <=5
they should increase by 3 instead
end

Here you have a backstage with 7sell in, 9 quality. Let's count the sell ins.
7=>6 increase by 2 quality = 11
6=>5 increase by 2 quality = 13
5=>4 increase by 3 quality = 16
4=>3 increase by 3 quality = 19!!!!!!!!!!

Thats 4 days. Where the final sell in/day is ending at 3. Going from 7>6>5>4. 2 of those days should be +2 each. The other 2 should be +3 each.
I know the answer it's testing for is +quality: 2,3,3,3
But the wording is very vague and confusing.

Starting items in the store are {Conjured Goblin Axe +5, 7, 13}, {Canned Laughters, 9, 12}, {Priss and the Replicants Backstage Passes, 7, 9}, {Conjured Goblin Axe +5, 9, 38}, {Zero Zone Kevlar Vest +1, 8, 22} and 4 days passed

OUTPUT:
Checking item 3: Priss and the Replicants Backstage Passes
Test Passed: Value == 3
Not the expected quality value - Expected: 20, instead got: 19

What if there's a 12 names in the array? Or 20 names? Your code would break. Refactor it so that it doesn't rely on hardcoding indexes to work.

Why would you write a for loop if you're just going to hardcode the indexes???
This isn't what the exercise was meant for IMO!

not even test cases

I"m getting a
"<NoMethodError: undefined method `*' for nil:NilClass> "
for one of the tests... everything else passes.

There are NO FUNCTIONS in ruby I am told. It's a method.

I did not see the stipulation. Sorry, but the code should work. Just check for syntax errors!
