The rendering of a template should be fast, since you will likely be doing it many times on a page.&lt;p&gt;&lt;pre&gt;&lt;code&gt;    ContactView = Backbone.View.extend({
      template: function() {
        var template = _.template($(&quot;#template-contact&quot;).html());
        return template.apply(this, arguments);
      },

      render: function() {
        // This is a dictionary object of the attributes of the models.
        // =&amp;#62; { name: &quot;Jason&quot;, email: &quot;j.smith@gmail.com&quot; }
        var dict = this.model.toJSON();

        // Pass this object onto the template function.
        // This returns an HTML string.
        var html = this.template(dict);

        // Append the result to the view&apos;s element.
        $(this.el).append(html);

        // ...
      }
    })
&lt;/code&gt;&lt;/pre&gt;
Note that the template is already on the page and has to be serialized by jQuery with the `_.template($(&quot;#template-contact&quot;).html());` line. It would be faster to already have the template in a JavaScript string, ready to be interpolated with your values.&lt;p&gt;Otherwise, for every view you will be fetching the template from the DOM. The difference in implementation would be from this:&lt;p&gt;&lt;pre&gt;&lt;code&gt;  &amp;#60;div id=&quot;template-contact&quot;&amp;#62;Mail me at &amp;#60;%= email %&amp;#62;&amp;#60;/div&amp;#62;
&lt;/code&gt;&lt;/pre&gt;
to this:&lt;p&gt;&lt;pre&gt;&lt;code&gt;  &amp;#60;script&amp;#62;var templateContact = &quot;Mail me at &amp;#60;%= email %&amp;#62;&quot;&amp;#60;/script&amp;#62;
&lt;/code&gt;&lt;/pre&gt;
It&apos;s a bit more work, but it reduces the amount of work that has to happen just to render one of many templates.</text><parent_chain></parent_chain></comment><story><title>Backbone patterns</title><url>http://ricostacruz.com/backbone-patterns</url><text></text></story>
