title: How would I parse a large TSV file in node.js?
body: <p>I'm extremely new to Node and JS. I have a large TSV file (1.5gb) that I need to read in and parse into either an array or JSON object. How would I go about doing that? I don't get an error when I try the code below but it doesn't even enter into it.</p>
  <pre><code>var d3 = require(&quot;d3-dsv&quot;);
  
  d3.tsvParse(&quot;amazon_reviews_us_Mobile_Apps_v1_00.tsv&quot;, function(error, data) 
  {
      var sum = 0;
      data.forEach(function(d) 
      {
          d.helpful_votes += d.helpful_votes;
          sum += d.helpful_votes;
      });
      console.log(&quot;Total Helpful Votes: &quot; + sum);
  });
  </code></pre>
  <p>Any help would be appreciated.</p>
