title: Use buffer in napajs
body: <p>I was trying to find multithreading support for JavaScript, and then came across <em>napa</em>, but in the list of supported API, there's <strong>no buffer</strong>.<br/> But in the project I've been working, we are passing buffer as an argument to functions which are required to be multithreaded, </p>
  
  <ul>
  <li>can we use node zone from another zone for computing calculations regarding buffer?</li>
  <li>If so how? If not, is there any other way or should I switch to using other library which unfortunately have much higher overhead cost?</li>
  </ul>
  
  <p>EDIT:- I am trying to implement multithreading where we require something like the following class to be transported:- </p>
  
  <pre><code>class Multi{
    a(){
      ...
      returns buffer; 
    }
    ... other properties
  }
  </code></pre>
