title: jQuery - .length returning "number is not a function"
body: <p>I'm new to jQuery and I'm still learning so I apologise if this is a silly question!</p>
  
  <p>Basically I'm trying to get the number of elements in my page with a certain class.  My searching tells me I need to use .length but it's not working for some reason.</p>
  
  <p>Any ideas at a quick glance at what may be causing the issue?</p>
  
  <pre><code>var item = $('.item')
  var itemWidth = item.width();
  var numberItems = item.length();
  console.log(numberItems);
  </code></pre>
  
  <p>Thanks!!</p>
