However, Object-Orientated Programming can actually absorb some of the lessons of Functional Programming to improve performance and reliability. This paper examines three ways in which Immutability, a common Functional Programming technique, can be used to develop immutable objects in Ruby.","url_abs":"https://arxiv.org/abs/2104.00379v1","url_pdf":"https://arxiv.org/pdf/2104.00379v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"immutability-and-design-patterns-in-ruby","repo_url":"https://github.com/corvideon/Immutable-Design-Patterns-in-Ruby","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
