      If the objects lack methods, it is better to simply use the literal object
      notation.

      var list = [
      {fname: "Dave", lname: "Smith"},
      {fname: "Mary", lname: "Brown"}];
      [color=blue]
      > //add object ("Sue","Wood ") to arrays
      > // How?[/color]

      list.push({fnam e: "Sue", lname: "Brown"});
