# Understanding Grids

Grids look cool because the lowest point that the represent, `0`, is
represented by ` `, a space. Enter characters like `$` and `a` to see
how single characters are translated to indexes by the Wax UTFGrid system.

=
var gi = new wax.GridInstance();

$('#char').keyup(function() {
  $('#result').text(
    gi.resolveCode(
      $(this).val().charCodeAt(0)
    ) || 0
  );
});
