ROT13 function (JavaScript)

String.prototype.rotate  = function() { 
            return this.replace(/[a-z0-9]/ig, function(chr) {
            var cc = chr.charCodeAt(0);
            if (cc >= 65 && cc <= 90) cc = 65 + ((cc - 52) % 26);
            else if (cc >= 97 && cc <= 122) cc = 97 + ((cc - 84) % 26);
            else if (cc >= 48 && cc <= 57) cc = 48 + ((cc - 43) % 10);
            return String.fromCharCode(cc);
                			});
		};

Reverse strings (CSS fallback)

String.prototype.reverse = function() {

    return this.split( '' ).reverse().join( '' ); 
      
      };
