title: Uncaught TypeError: Cannot read property 'noConflict' of undefined
body: <p>I'm new to jQuery and I'm getting an error in a web page of mine as follows:
  "Uncaught TypeError: Cannot read property 'noConflict' of undefined"</p>
  
  <p>I'm using jQuery in my page and it was suggested to me that I should use</p>
  
  <pre><code>var $j = jQuery.noConflict();
  </code></pre>
  
  <p>Is there a way I can unsure I don't receive the undefined error when setting my $j variable?</p>
  
  <p>Thanks in advance.</p>
