ABAP vs. C# vs. PureScript vs. Sumocode Comparison Chart

ABAP (Advanced Business Application Programming) is SAP’s proprietary fourth‑generation programming language, purpose‑built for mass data processing in SAP business applications. Utilized within SAP NetWeaver, it enables companies running SAP ERP and S/4 HANA to tailor systems precisely to their needs. ABAP is a multi‑paradigm language that supports procedural, object‑oriented, and other programming styles. It can seamlessly interoperate with languages such as Java, JavaScript, and SAPUI5. ABAP embraced object orientation with release 4.6C (2000) and saw even greater efficiency gains in ABAP 7.4/7.5, cutting code length by up to 50% via richer syntax, enhanced Open SQL, ABAP Managed Database Procedures, and Core Data Services (CDS) Views. The arrival of SAP HANA in 2011 shifted much processing into the in‑memory database layer, enabling real‑time operations and unlocking powerful new programming possibilities.

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.
