because despite having its dangers, the solution is beautiful to see, in the context of codewars, this type of solution comes out ahead... multiple 'ifs' are sometimes not very elegant..

I just read some comments below that clearly state you shouldn't use eval() for these kinds of purposes because eval() will
run absolutely anything, therefore it's potentially extremely hazardous to use it. So, explain to me: why the 724 Best Practices?

did the same lol

Nice!

convert value1 and value 2 to strings first. Your code doesn't evaluate the values of value1 and value2. Say value1 = 1 and value2 = 3, your code is trying to evaluate value1 + value2 whereas it should be evaluating 1 + 3.

clever, I'm borrowing this!

no he mean he use "join" method while he can do this like this

why you when to join first?

:D

that's some crazy obfuscation there.

Nice kata, requires some thorough research just like many other ones.

LOL

good
