ABAP vs. C# vs. Deno vs. Java 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.

Deno is a simple, modern and secure runtime for JavaScript, TypeScript, and WebAssembly that uses V8 and is built in Rust. Deno comes with a manual which contains more in depth explanations about the more complex functions of the runtime, an introduction to the concepts that Deno is built on, details about the internals of Deno, how to embed Deno in your own application and how to extend Deno using Rust plugins. Next to the Deno runtime, Deno also provides a list of audited standard modules that are reviewed by the Deno maintainers and are guaranteed to work with a specific Deno version. These live in the denoland/deno_std repository.
