title: Create Long variable Javascript
body: <p>I need to create a Long variable using JavaScript, like you can do normally in Java by executing this code:</p>
  
  <pre><code>long n = 3;
  </code></pre>
  
  <p>My problem is that I need "n" to be very very big, exceeding the range of an integer, because I'm doing big number calculus. Do you know any way to create that? The "var" type of data is long enough for this?</p>
