title: Push new data to external JSON file
body: <p>I'm trying to push a new object into an external Javascript document but I am having problems pulling in the JSON file to write to. I have an external, local file called check.json. </p>
  
  <p>How do I call the external json file correctly in node?</p>
  
  <pre><code>var newData = JSON.parse(check.json);
  
  newData.check.push({
     cheap: $el.text()
  });
  
  check.json = JSON.stringify(newData);
  </code></pre>
