title: split String, then count and convert to json array
body: <p>I have a url to read file in my nodejs application. What I wanna do three things in here. First read file through that url. Second I want to addition the count if value is the same and final is convert to json. Here is the format that I want.</p>
  
  <pre><code>[ 
   {
     value : '106',
     count : 1 
   },{
     value : '109',
     count : 2
   }
  ]
  </code></pre>
  
  <p>Here is the file format </p>
  
  <blockquote>
    <p>value, count, 106, 1, 109, 2, 111,2</p>
  </blockquote>
  
  <p>I try to use csv-parse and csvtojson node module but it different to manipulate the way the I want. Those modules return the json but I want to manipulate the json like if value are the same, I want to addition the count.</p>
  
  <p>Thanks. </p>
