Not sure what the test cases are for the Fibonacci sequence (just happened to pick that one first), but it gives an error for my code, and I'm not able to figure out why. (please ignore my bad variable names)

  function(index) {
   var fib = [0,1];
   for(var i=2; i<index; i++){
     fib[i]=fib[i-2]+fib[i-1];
   }
   return fib[index-1];
  }

Your function will return 2 for index = 4, whereas it's expecting 3.

Then are the instructions not clear enough, or am I just missing something....

From the website: "For example, the sequence [0, 1, 1, 2, 3, 5, 8, 13, 21, 34] forms the first ten entries of the Fibonacci sequence." Entering 4 should return 2 in this case, which is correct? I don't get it.

Index 4 is the fifth element, 3. Index 0 is the first element (a zero).

Reread the examples.
