/* ==========================================================================
  Gets the element at index n of array. If n is negative, the nth element from the end is returned.

  Definition: _.nth(array, number)

  Example Usage:

  const suspects = ["Colonel Mustard", "Miss Scarlett", "Prof Plum"];

  console.log(_.nth(suspects, 0));
  // => "Colonel Mustard"

  console.log(_.nth(suspects, 2));
  // => "Prof Plum"

  console.log(_.nth(suspects, -1));
  // => "Prof Plum"

  ========================================================================== */

_.nth = function(array, index) {
  // TODO: Write the solution here
  if (index < 0) {
    return array[array.length + index];

  return array[index];

const weapons = [
  "Lead Pipe",

// We should get the first element of the array.
console.log(_.nth(weapons, 0), "Revolver");

// NEAT: _.nth(weapons, 0) is equivalent to _.head(weapons)

// We should get the second to last element of the array.
console.log(_.nth(weapons, -2), "Knife");
