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.
