Great kata but the key order thing is annoying. Either include the expected order in the description or use Chai instead of Codewars' test framework.

Issue still exists.

Probably Test.assertSimilar compare Object.keys array, JSON.stringify or something like that.

Please use other compare function.

Being the result an object, I don't think the sorting order is important.
Did it fail you if you try to sort the results differently? Have you tried?

The comment below the result is sort by key like this:['ATF6', 'CREB', 'cMyc', 'Gata1', 'AhR']. This information should be in the description of the kata.

Sorry, I am afraid I don't quite get your issue. Could you elaborate more?

why on earth is this marked as spoiler?

order of results not specified

the result is sort by key like this:['ATF6', 'CREB', 'cMyc', 'Gata1', 'AhR']

it happens because

some transcription factors could have overlapping binding sites with others (or with themselves).

So the ATF6: "TGACGT" binds the sequence "TGACGTGACGT" twice at index 1 and 6 with an overlapping T:

TGACG|T|
     |T|GACGT
TGACG|T|GACGT
1     6

the "TGCGTGCGTG" sequence relative to AhR: "TGCGTG" contains an overlapping TG:

TGCG|TG|
    |TG|CGTG
TGCG|TG|CGTG
1    5

Hope it is clear now, cheers!

It seems pretty interesting Kata, but i Don't understand it. Why ("TGACGTGACGT"),{ ATF6: [ 1, 6 ] }), ("TGCGTGCGTG"),{ AhR: [ 1, 5 ] }) ?
Who could explain please?

....Sort the values

have you tried to sort the result in a final step?

I have the same problem :(.

I seem to get everything right but the order of the result object properties prevents me from passing all the tests. Shouldn't I pass as long as the object has all the keys and its values regardless of the order of the properties?

Expected: {"ATF6":[5],"cMyc":[1]}, instead got: {"cMyc":[1],"ATF6":[5]}

It has been a nice kata to do! I have learnt new things about RegExp working with this one.

Thanks! :)
