title: EJS: pass a variable to the included file
body: <p>I'm using EJS as a part of my front-end dev stack. 
  For example my normal index.ejs looks like that:
  <div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;%- include parts/header.ejs %&gt;
  
    &lt;%- include parts/navigation.ejs %&gt;
      
      &lt;!-- HTML content: divs, spans, etc. --&gt;
    
  &lt;%- include parts/footer.ejs %&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>What I want is to pass somehow a variable with the include &lt;%- include parts/footer.ejs?<strong>variable=value</strong> %> and want to read it in the included file, to conditionally show/hide some parts of the content. </p>
  
  <p>I can't find the way to do it. Is it possible with EJS?</p>
