Haskell is described as 'Advanced purely-functional programming language. An open-source product of more than twenty years of cutting-edge research, it allows rapid development of robust, concise, correct software' and is a popular programming language in the development category. There are more than 50 alternatives to Haskell for a variety of platforms, including Linux, Mac, Windows, BSD and Web-based apps. The best Haskell alternative is Python, which is both free and Open Source. Other great apps like Haskell are Java, Rust, PHP and C++.
Hack is a programming language for HHVM that interoperates seamlessly with PHP. Hack reconciles the fast development cycle of PHP with the discipline provided by static typing, while adding many features commonly found in other modern programming languages.
Temper is a programming language and toolchain for making libraries that can be used natively from any other language.

Vala is a new programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements and without using a different ABI compared to applications and libraries written in C.
Unison is a statically-typed functional language with type inference, an effect system, and advanced tooling. It is based around a big idea of content-addressed code, in which function are identified by a hash of their implementation rather than by name, and code is stored as...
Luau (lowercase u, /'lu.a?/) is a fast, small, safe, gradually typed embeddable scripting language derived from Lua.
Pluto is a superset of Lua 5.4 designed for general-purpose programming. While being remarkably compatible with Lua 5.4 source-code & bytecode, it enhances the standard library & adds more than a dozen highly-desired syntaxes such as switch statements, compound...
