title: Underscore conditionals and operations for this template?
body: <p>New to underscore. How do I write an "each" function for each post so that only the latest post is appearing? I know the logic is something like this  </p>
  
  <pre><code>&lt;% _.each(posts, function(post, index) { %&gt;
  &lt;% if(index % 3 == 0) { %&gt; 
  </code></pre>
  
  <p>But I only want the LAST post to show. In addition to that, I'm trying to figure out the logic I wrote in comments before each section, I'm having trouble trying to figure out the <strong>if/then</strong> logic code if ONLY an image appearing, if ONLY text, and then when if an image AND text appear together. </p>
  
  <pre><code>&lt;!-- TEXT ONLY --&gt;
  &lt;p&gt;&lt;%= post.message %&gt;&lt;/p&gt;
  &lt;!-- /TEXT ONLY --&gt;
  
  &lt;!-- IMAGE ONLY --&gt;
  &lt;img class="imgonly" src="&lt;%= post.image %&gt;"&gt;
  &lt;!-- /IMAGE ONLY --&gt;
  
  &lt;!-- TEXT + IMAGE --&gt;
  &lt;p&gt;&lt;%= post.message %&gt;&lt;/p&gt;
  &lt;img class="imgtext" src="&lt;%= post.image %&gt;"&gt;
  &lt;!-- /IMAGE + IMAGE --&gt;
  
  &lt;!-- TEXT + IMAGE + LINK + LINK SUMMARY --&gt;
  &lt;p&gt;&lt;%= post.message %&gt;&lt;/p&gt;
  &lt;p class="link"&gt;&lt;a href="&lt;%= post.link %&gt;" target="_blank"&gt;&lt;%= post.link_title %&gt;&lt;/a&gt; - &lt;%= post.link_summary %&gt;&lt;\/p&gt;
  &lt;img class="imgtext" src="&lt;%= post.image %&gt;"&gt;
  &lt;!-- /IMAGE + IMAGE + LINK + LINK SUMMARY --&gt;
  
  &lt;!-- IMAGE + LINK + LINK SUMMARY --&gt;
  &lt;p class="link"&gt;&lt;a href="&lt;%= post.link %&gt;" target="_blank"&gt;&lt;%= post.link_title %&gt;&lt;/a&gt; - &lt;%= post.link_summary %&gt;&lt;/p&gt;
  &lt;img class="imgtext" src="&lt;%= post.image %&gt;"&gt;
  &lt;!-- /IMAGE + LINK + LINK SUMMARY --&gt;
  
  &lt;!-- PLACEHOLDER --&gt;
