title: How to add two big numbers in javascript?
body: <p>I have two text boxes. Each will take input up to thousand digits.</p>
  
  <p>Now i want to add these two numbers. My question is what data type should i use to store the result?</p>
  
  <p>I have tried this:   </p>
  
  <pre><code>&lt;script&gt;
     var x = 'Thousand digit of number'
      var y = 'Thousand digit of number'
      var z = x + y
  &lt;/script&gt;
  </code></pre>
  
  <p>but i am getting result in exponential form. How to store the result and display it?</p>
