JavaScript vs. PureScript vs. Scala vs. XSharp (X#) Comparison Chart

PureScript is a strongly typed, purely functional programming language that compiles JavaScript. It enables developers to build robust web applications, web servers, and mobile apps using functional programming techniques. PureScript offers features such as algebraic data types, pattern matching, row polymorphism, extensible records, higher-kinded types, type classes with functional dependencies, and higher-rank polymorphism. The language emphasizes strong static typing and pure functions, ensuring code reliability and maintainability. Developers can compile PureScript code into readable JavaScript, facilitating seamless integration with existing JavaScript codebases. The ecosystem includes an extensive collection of libraries, excellent tooling, and editor support with instant rebuilds. An active community provides numerous learning resources, including the PureScript book, which offers practical projects for beginners.

X# is an open-source development language for .NET, based on the xBase language. It comes in different flavors, such as Core, Visual Objects, Vulcan.NET, xBase++, Harbour, Foxpro, and more. X# has been built on top of Roslyn, the open-source architecture behind the current Microsoft C# and Microsoft Visual Basic compilers. We have added a new options page (tools/options/text editor/X#) where you can control which suggestions the editor will suggest in the "general" code completion list. Code completion after a colon or dot will show namespaces, types, members, etc. And code completion after AS or IS will show types and namespaces. Several preprocessor fixes to make the preprocessor more compatible with FoxPro and Xbase++. We have also added the #if and #stdout commands. We added several smaller fixes in the RDD system to improve the compatibility with Visual Objects, XBase++ and FoxPro.
