This is 5kyu kata? Are you joking me?

mine : 6141381611
???

expected NaN to equal NaN
I don't know
wtf? what happened

the value of 'x' is 10,it is only one number.and ai which means the number character value at the i-th position. For example, a1 is the 18th verification code of the ID number(if a1 was 'x',the value of it will be 10);

I can't understand you

Thank you for your advice,I will change it

only ai*wi mod 11 === 1. It can be true.916745198604207473 (441 % 11 === 1)

OK

it has solved

Wi is one array.
It must be mode by 11,and the result must be 1
The range for valid date means the truth date number

It has solved.

Why I can't use Date.prototype.toLocaleDateString(loc)to change the time place.
For example, at my vscode -> getDate(1481020142, "ko-KR") output:2016. 12. 6.
but when I test the case. output:2016-12-6
why ???

OK,thank your suggestion.I will check my code.

But in my local Vscode,it has "fries" in other category
