Fantom (previously known as Fan) is a general purpose object-oriented programming language that runs on the Java Runtime Environment (JRE), JavaScript, and the .NET Common Language Runtime (CLR).
Fantom is, generally speaking, a strongly and statically typed language with a familiar C-style curly brace syntax.
Fantom is a pure OO language in that everything is an object you can call methods on. The language is currently in development. It is robust and stable and ready to use in production.
Features include:
- Compiles to either JVM or .NET bytecode.
- Supports imports of Java Classes and modules with some limitations.
- Integer is 64-bit. Unlike Java and C#, Fantom does not have Long or Short integer types.
- Static typing.
- Supports the same primitive literals as Java or C#, plus some that are typically found in higher level scripting languages.
- Reuses most the same expression syntax as Java and C#.
- Supports interpolation.
- Supports first class functions and closures – the standard APIs make heavy use of functional programming.
- Serialization and deserialization of classes to/from strings.
- A Ruby-like syntax for using closures.
- Mixins.
- Declarative syntax for constructing new objects.
- All threads in Fan have the ability to pass messages to other threads.
- Literal syntax for programming with lists, maps, etc.
