title: Return a new array with the first and last element of the passed array
body: <p>I am not sure what I am missing. Need the new array to return the first and last element of the passed array.</p>
  
  <pre><code>var firstAndLast = function(array){
  
    var newArray = new Array();
    newArray [0] = array[0]
    newArray [1] = array[3]
    return plate;
  }
  
  For Example:
  var array = ['one', 3, 'cool', 4];
  firstAndLast(array); // returns ['one', 4]
  </code></pre>
