title: TypeError: $.get is not a function
body: <p>I have a function in JavaScript.</p>
  
  <pre><code>$scope.getBanksyUrl = (data) =&gt; {
      $.get('banksyurlservlet', function(data) {
          //return the url here
      });
  }; 
  </code></pre>
  
  <p>But when I invoke this function, I see in my JS console:</p>
  
  <pre><code>TypeError: $.get is not a function
