I used a solution similar to this one at first and passed but when I came back and tried an optimized version the optimized code does pass but this old version won't anymore. I think sometimes you can get lucky with this approach if the randomized tests are smaller numbers, but in general they expect the solution to be more optimized. This should probably be higher than kyu 6 imo because 7's generally don't care so much about optimization and this unoptomized approach is the more obvious answer.

CodeWars JS challenges use NodeJS and some katas use older versions of Node. This one uses Node 8.1.3 which is from 2017. BigInt wasn't supported until Node 10.4.0. You can see on the practice page which version of Node it's using. Sometimes it lets you select between a few different versions but this one only allows 8.1.3..

Read this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array there is one method that will be useful.

Remove those double quotes, and check this:

Note that name will be an array consisting of one or more values that should be joined together with one space between each

Your code would work only with two values.

yeah task is not wrong:=)) I solved too

I just solved it and seems to be OK.

What would be wrong about it?

wtf? what is wrong? i cant decide in python coz this task is wrong

Not anymore.

Fixed.
