function hello_world() {
    var message = "b.+.b.=.d.!. .27.0.1.24. .44.8.12. .2.14.12.8.13.6. .18.14.14.13. .38.0.17.2.7. .c.a.b.e",
        characters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ',
        index, new_message = '', new_char = '';

    message = message.split('.');
    for (var i = 0, ln = message.length; i < ln; i++) {
        index = characters.indexOf(message[i]); 
        if (index === -1) {
          new_char = characters[message[i]] || message[i];  
        } else {
          new_char = index;
        }
        new_message += new_char;
    }
    return new_message; 
}
