title: Reading from an external file in Javascript (without jQuery)
body: <p>I'm looking for a way to read from an external text file <code>map.txt</code> (allocated in my own server, not in the client's computer) and to store the data contained in it in a bi-dimensional array <code>map[][]</code> using Javascript.</p>
  
  <p>The <code>map.txt</code> file would be filled with numbers and each of it's rows has a fixed length:</p>
  
  <pre><code>21123301201200
  12030201303321
  22321321021312
  12312310001230
  12312321221220
  </code></pre>
  
  <p>So, I want it to store it in the bi-dimensional array <code>map</code> in such a way that <code>map[0][0] = 2</code> and <code>map[13][4] = 0</code> -in this example-. Is this even possible to do? And if so, how is it done?</p>
  
  <p>Thanks!</p>
