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 C (programming language). Other great apps like J are Rust, Lua, C# and Go (Programming Language).
