title: JavaScript - Array newLength from MDN tutorial
body: <p>I'm working through a tutorial on Arrays from MDN and I can't understand HOW the code line "newLength" is returning the value of 7? I understand that there are 7 items in the array but <strong>how is it doing it</strong> when there is no ".length" on the end. </p>
  
  <hr>
  
  <p>My Code -</p>
  
  <pre><code>var myData = 'Manchester,London,Liverpool,Birmingham,Leeds,Carlisle';
  
  var myArray = myData.split(',');
  
  var newLength = myArray.push('Bristol');
  
  console.log(myArray);
  
  console.log(newLength);
  </code></pre>
  
  <hr>
  
  <p>This is the return result within console - </p>
  
  <pre><code>[ 'Manchester',
  
    'London',
  
    'Liverpool',
  
    'Birmingham',
  
    'Leeds',
  
    'Carlisle',
  
    'Bristol' ]
  
  7
  </code></pre>

  <p>Thx for your help!</p>
