WebAssembly or WASM for short, is an open standard and binary instruction format for a stack-based virtual machine. WebAssembly run in all modern web browsers at near-native performance and provides languages such as C/C++ and Rust with a compilation target so that they can run on the web. The language is designed to run alongside JavaScript, allowing both to work together, while simultaneously redefining the web's capability.

Silq is a free and open-source high-level programming language specifically for quantum computing. The language is openly developed by ETH Zürich and provides a strong static type system.

A Microsoft developed domain-specific programming language used for expressing quantum algorithms. Q# share similar structures and elements with popular languages like Python, C#, and F#. The language comes bundled with the QDK (Quantum Development Kit) and quantum simulators, while also being extensible with Q# libraries. With Q# developers can build quantum algorithms used for quantum computing with a basic procedural model for writing programs with loops, if/then statements, and common data types.

A general purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. Objective-C was specifically designed for the Apple ecosystem and their respective application programming interfaces, Cocoa and Cocoa Touch for building applications for macOS and iOS. Since 2014 the Apple ecosystem rely on their new programming language Swift.

Developed by Facebook as free and open-source dialect of PHP, Hack is a programming language for the HipHop Virtual Machine. Hack is licensed under the MIT License and allows developers to use both dynamic typing and static typing.

Cython is a free and open-source optimising static compiler and a superset of the programming language Python. Cython is designed to give C-like performance for code written with Python. The language also provides an optional C-inspired syntax and the ability to create CPython extension modules.

Eiffel is an free and open-source object-oriented programming language designed at Eiffel Software by Bertrand Meyer back in 1985. Bertrand Meyer had one goal in mind when he created the language, the goal of increasing the reliability of commercial software development. Today Eiffel comes with its own IDE (Integrated Development Environment) called EiffelStudio, the software can be used to write Eiffel code in a single user interface that includes a compiler, interpreter, debugger, browser, metrics tool, profiler, diagram and code inspector.

With Ceylon developers can write software that runs on the JVM (Java Virtual Machine) or complied to JavaScript. Ceylon is an object-oriented, strongly statically typed programming language with an emphasis on immutability. The language was first created by Red Hat in 2011, but is now maintained by the Eclipse Foundation.

A free and open general-purpose, object-oriented programming language developed by Ary Borenszweig, Juan Wajnerman, Brian Cardiff and a community with over 300 contributors. Crystal is statically type checked, which means that all code errors will be caught at compile time, rather than fail on runtime. Crystal provides an easy-to-learn syntax similar to Ruby, while at the same time producing performance similar to that of the programming language C.
