//A Needle in the Haystack
/*Can you find the needle in the haystack?

Write a function findNeedle() that takes an array full of junk but containing one "needle"

After your function finds the needle it should return a message (as a string) that says:

"found the needle at position " plus the index it found the needle, so:

Example(Input --> Output)
["hay", "junk", "hay", "hay", "moreJunk", "needle", "randomJunk"] --> "found the needle at position 5" 
["hay", "junk", "hay", "hay", "moreJunk", "needle", "randomJunk"] --> "found the needle at position 5" 
*/

function findNeedle(haystack) {
  return "found the needle at position " + haystack.indexOf("needle");
}
/*
function findNeedle(haystack) {
  for (let i = 0; i < haystack.length; i++)
    if (haystack[i] === "needle") {
      return "found the needle at position "+ i;
    }
}
