title: Find the smallest and largest value in an array with JavaScript
body: <p>I am trying to write an algorithm that finds and smallest and largest value in an array, and the second largest and second smallest.</p>
  
  <p>I tried with the following: </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>numbers = [2, 4, 9, 2, 0, 16, 24]
  
  var largest = numbers[0];
  var smallest = numbers[0];
  
  for (var i = 1; i &lt; numbers.length; i++) {
  
    if (numbers[i] &gt; largest) {
      largest = numbers[i];
    } else if (numbers[i] &lt; smallest) {
      smallest = numbers[i];
    }
  
    console.log(largest);
    console.log(smallest);
  }</code></pre>
  </div>
  </div>
  </p>
  
  <p>This does not seem to work and just prints out the array...what am I doing wrong?  </p>
