You are modifying the original values in the dictionary, upon computing the summation, it will take into account unnecessary values in the previous iterations

This is the only solution which I can understand easily.

Wasn't familar with the formatting So looked for it in the stackoverflow and realised your wonderfull simple solution..

Thanks

Brilliant :)

Need some hint

Thank you.

that's great that you're obsessed with solving the kata but NOBODY WANTS YOU YELLING AT THEM LIKE THIS BECAUSE THINGS ARE NOT AS YOU WISH THEY WERE. if you want to see tests on a kata such as this one you are going to have to use console.log() to print the inputs. just because your code is passing the basic tests guarantees nothing, and if a knowledgeable coder can actually see your code and tell you there's a problem, the right thing to do would be say, "Thank you for reviewing my code", and get back to work.

console.log...

As I said before, I am just learning javascript and I can not revise my code if I can not see where it goes wrong ! I WANT TO SEE THE RANDOM TEST so I can determin what is wrong with my code ! JUST saying that I have a bug and I have to revise it from the beginning, is not helping me at all ! The problem is that I am obsessed with this kata ! ALL THE OTHER KATAS I HAVE COMPLETED, show all the random tests, even if there where 200 tests. Sometimes there are specific exceptions!

Please, be very attentive because your code has a serious bug!
Revise it once again from the beginning...
