Fantom is an elegant and practical programming language with the following features:

* Portability: Write code portable to the Java VM, .NET CLR, and JavaScript in the browser.
* Familiar Syntax: Java and C# programmers will feel at home with Fantom's evolutionary syntax.
* Mixins: Interfaces but with implementation.
* Concurrency: Tackle concurrency with built-in immutability and actor model.
* Object Oriented: Everything subclasses from Obj. Value types when you need the performance.
* Functional: Functions and closures are baked in.
* Static and Dynamic Typing: Don't like the extremes - take the middle of the road.
* Serialization: Built-in "JSON like" serialization syntax makes Fantom ideal for declarative programming too.
* Elegant APIs: We're quite obsessive about providing all the key features required for a standard library, but with much less surface area than the APIs found in Java or .NET.
* REST: URI literals and a unified namespace of resources identified with URIs.
