Parameter explanation:

attribute: It specifies the property of a defined model.

Let's take an example to deploy this property.

 <!DOCTYPE html>
   <head>
      <title>Pluck Collection Example</title>
         <script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>

         <script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script>
   </head>
   <body>
      <script type="text/javascript">
var subjects = new Backbone.Collection([
  {name: "Java"},
  {name: "PHP"},
  {name: "Oracle"}
]);

var names = subjects.pluck("name");
document.write("Attributes returned on pluck: <br/>",subjects.pluck('name'));

      </script>
   </body>
</html>
