general-purpose programming language

TypeScript (TS) is a high-level programming language that adds static typing with optional type annotations to JavaScript. It is designed for developing large applications. It transpiles to JavaScript. It is developed by Microsoft as free and open-source software released under an Apache License 2.0.

Clojure (, like closure) is a dynamic and functional dialect of the programming language Lisp on the Java platform.

ECMAScript (; ES) is a standard for scripting languages including JavaScript, JScript, and ActionScript. It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. It is standardized by Ecma International in the document ECMA-262.

CoffeeScript is a programming language that compiles to JavaScript. It adds syntactic sugar inspired by Ruby, Python, and Haskell in an effort to enhance JavaScript's brevity and readability. Some added features include list comprehension and destructuring assignment.

Haxe is a high-level cross-platform programming language and compiler that can produce applications and source code for many different computing platforms from one code-base. It is free and open-source software, released under an MIT License. The compiler is written in OCaml. It can be run in server-mode to provide code completion for integrated development environments (IDEs).

Cython () is a superset of the programming language Python, which allows developers to write Python code (with optional, C-inspired syntax extensions) that yields performance comparable to that of C.
