J is described as 'High-level, general-purpose programming language that is particularly suited to the mathematical, statistical, and logical analysis of data. It is a powerful tool for developing algorithms and exploring problems that are not already well understood' and is a programming language in the development category. There are more than 50 alternatives to J for a variety of platforms, including Windows, Linux, Mac, BSD and Self-Hosted apps. The best J alternative is Java. It's not free, so if you're looking for a free alternative, you could try Java or Rust. Other great apps like J are C++, Lua, C# and Go (Programming Language).
Yon is an experimental, topos-oriented programming language: a compiled language whose semantics are drawn from category theory (elementary topoi, Heyting algebras, directed type theory) and whose runtime stores every value in a content-addressed heap built on the Leech lattice ?
Squirrel is a high level imperative, object-oriented programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games.
