A5 employs a completely new, ground up rethink of how close object oriented JavaScript can mirror classical OOP languages like C# and Java, while retaining the performance benefits of the prototype object model and working in zero compile, native JavaScript objects.

A5 Language Features:

Classes, interfaces, enums, and mixins
Import statements and validated packages
Instance and static members
Real constructors, named to match their owner class
Superclass accessors
Dealloc destructors
Validation enforced override and final method declarations
Reflection on classes and methods
Attributes for applying meta information to classes and methods
Singleton, Abstract, and Final class declarations
Aspect oriented cross-cutting (before/after/around) for methods

Validated on: IE 5.5+ FF2+ Chrome Safari 3.2+, CommonJS compliant

Defining a class: hello world

a5.Package('sampleApp')

     .Class('Foo', function(cls, im){

          cls.Foo = function(){
               console.log('Hello World!');
          }
});

a5.Create(sampleApp.Foo);

a5.Package('sampleApp')

.Class('Foo', function(cls, im){

cls.Foo = function(){

console.log('Hello World!');

}

});

a5.Create(sampleApp.Foo);
