Objeck is an object-oriented computing language with functional features. The language was based upon the author's use of Java and Scheme. In the language, all data types are treated as objects and first-class functions that support closures.

The programming environment consists of an optimizing compiler, command-line debugger, and virtual machine with associated garbage collector and JIT compiler. The compiler emits binary bytecode that is executed by the runtime system. The 64-bit runtime JIT compilers support ARM64 and AMD64 machine code targets for macOS, Linux and Windows.

+{{language|Objeck
-The '''Objeck programming language''' is an object-oriented (OO) computing language that has ties with Java, Pascal and indirectly Ruby. In this language, all data types are treated as objects. The language contains all of the "basic" features of a general-purpose (Turing complete) programming language with an emphasis placed on OOP simplicity. The language consists of a compiler and virtual machine with associated garbage collector and JIT compiler. The compiler emits binary byte code that is executed by the runtime system. The runtime system has the ability to translate the byte code into IA-32 native machine code.

+The programming environment consists of an optimizing compiler, command-line debugger, and virtual machine with associated [[Garbage collection|garbage collector]] and [[JIT]] compiler. The compiler emits binary [[bytecode]] that is executed by the runtime system. The 64-bit runtime JIT compilers support ARM64 and AMD64 machine code targets for macOS, Linux and Windows.
-===Features===
-* Support for object-oriented programming (including: virtual classes, enums, functions, methods, etc.)
-* Support for polymorphic methods and functions
-* "public" and "private" methods classifications
-* Native runtime JIT support for IA-32 architectures (currently working on AMD64 support)
-* Automatic memory management (mark and sweep garbage collection)
-* Dynamic type variable binding
-* Class library support (console, strings, files, sockets, directories, vectors, linked lists and balanced binary trees, etc.)
-* String object support
-* Support for class bundles
-* Native platform support for Windows, Linux and OS X
-* Command line debugger
-* Platform independent optimizations (short-circuit logic, constant folding, strength reduction, instruction simplification and method inlining- WIP)
-* Heavy use of the SSE3 instruction set in order to support fast decimal calculations
