Can you explain why?

I know right. That's just way too many lines😂!!!

Not anymore, no. I was pointing out that the kata's tests were horrible. It's been fixed.

@koushik72, magic constants are numbers which appear in a program.
Often repeatedly.
For example, if you had a conversion program and used the conversion factor as a number everywhere, that would be a magic constant.
Having magic constants in a program is generally a bad thing because the number doesn't express what it is being used for. And is vulnerable to typos.
It's better to make a constant variable equal to the number, e.g., CONVERSION_RATE, and use it instead, making the code clearer.

I don't think it applies here, as 100 being used for percentage calculations is well known and it is hard to come up with a variable name for that 100.

I am not good in js. Can you please explain what is magic constants? Thanks.

Concerning code duplication, I have submitted a new solution that you might like better.

As for magic constants, are you talking about the value 100 ? If it is not obvious that it is used to compute a percentage, it could be explained in a comment.

Indeed, I would prefer the simplified condition to the one in this case. It will be slightly more efficient code, it will be shorter code, etc.
