title: How To Obtain Cumulative Sum Array Using Underscore.js?
body: <p>I have an <code>array = [1,2,3,4,5]</code> and would like to obtain the cumulative sum <em>array</em> using <a href="http://underscorejs.org/" rel="nofollow">underscore.js</a>. </p>
  
  <p>The result I want is:</p>
  
  <pre><code>[1,3,6,10,15]
  </code></pre>
  
  <p>I want the <em>array</em> not the cumulative sum 15 as a value. Any help would be appreciated.</p>
