Ceylon (programming language)

Ceylon is an open source, object-oriented programming language created in 2011 by Gavin King at Red Hat. It is strongly and statically typed and places an emphasis on immutability. Ceylon programs run on the Java virtual machine and can also be compiled to JavaScript. The design aims for source code that is readable and predictable, and for a language that is friendly to tools, modular and capable of metaprogramming. The Programming Language Database lists static typing, type inference and operator overloading among its features, and names Java, Scala, Smalltalk, ML, Lisp, TypeScript, Dart and Fantom as related languages. The project was developed in the open on GitHub under the Eclipse organisation, and its compiler and tools were written largely in Java and JavaScript, with sample programs defining shared functions and classes.
