As a part of this Kata, you need to create a function that when provided with a triplet, returns the index of the numerical element that lies between the other two elements.

middle.js

var gimme = function (inputArray) {
  // Clone the input array.
  var clonedArray = inputArray.slice(0);
  // Sort it in ascending order.
  clonedArray.sort(function(a, b){
    return a-b
  });
  return inputArray.indexOf(clonedArray[1]);
};
