I thought it wasn't allowed to use eval... meh. :(

Now I understood what you meant when saying that I can't work my way through the digits of a number in that way. I see now that JavaScript doesn't support what I was attempting, so I changed a bit and now works!

Hahaha, cheers!

I don't get it, why not? It seems just fine for my.

Strangely this works fine for Java.

I even tried to change the "for in" loop to a traditional "for" loop and still nothing. Maybe is something in JavaScript that doesn't support ? :(

You can't work your way through the digits of a number in quite that way...

I'm not being able to pass on the test but I'm pretty sure my code is right, could someone help me see what is happening ?

function narcissistic( value ) {
  var i, a, b;
  if (value < 10){
    return true;
  }
  else{
    for(i in a=b=value)b-=Math.pow(a[i],a.length)
    return(!b);
  }
}

See, I get reproved in the test case for 153 ("Test Failed: 153 is narcissistic"), but in my function goes like this:

for(i in a=b=153)b-=Math.pow(a[i],a.length)

wich goes 3 times, since a.length is 3 so:

#1º) 153 - Math.pow(1,3) = 153 - 1 = 152

#2º) 154 - Math.pow(5,3) = 152 - 5^3 = 27

#3º) 27 - Math.pow(3,3) = 27 - 3^3 = 0

Then again, my function returns (!b), since b = 0, !0 = true

Why my code is not being accepted ?

Hope someone help me out, cheers!

Ok, I see what I did now.. ahahaha, I was "printing" instead of "returning".
shame on me!

Thanks anyway.

I'm sorry ogryzek, since you've marked your reply as a spoiler and I didn't solve the problem because I'm getting the error, I can't un-flag it, so I would appreciate if you could tell me a hint in a different way.

Cheers ! =)

While working out with the Instructions and Output tabs there's this:

"Tip: You can press Cmd + I to toggle between Instructions and Output tabs."

I don't know if this site was design only for Mac users, but in Linux and Windows we don't have the "Cmd" button.

I suggest you guys change to a more universal pattern.

Anyway, I really enjoyed this design, by far the best I've seen in a platform like this.

Cheers!

Ok, I'm not getting it, here's my code:

def solution(value)
@new_value = "%05d" % (value)
print "Value is #{@new_value}"
end

What is wrong? It results Exactly "Value is "5 digit formatted value""
