You would use it against templates written like this (it doesn’t have to be in this particular manner – but it’s a style that I enjoy):

<script type="text/html" id="item_tmpl">

  <div id="<%=id%>" class="<%=(i % 2 == 1 ? " even" : "")%>">

    <div class="grid_1 alpha right">

      <img class="righted" src="<%=profile_image_url%>"/>

    </div>

    <div class="grid_6 omega contents">

      <p><b><a href="/<%=from_user%>"><%=from_user%></a>:</b> <%=text%></p>

    </div>

  </div>

</script>

 

You can also inline script:

<script type="text/html" id="user_tmpl">

  <% for ( var i = 0; i < users.length; i++ ) { %>

    <li><a href="<%=users[i].url%>"><%=users[i].name%></a></li>

  <% } %>

</script>
