| Records existed before and influenced OOP, and they exist outside of OOP today, in imperative and pure functional languages:
https://en.wikipedia.org/wiki/Record_%28computer_science%29 Summary by Wikipedia is pretty good: >Object-oriented programming (OOP) is a programming paradigm based on the concept of objects,[1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods). In OOP, computer programs are designed by making them out of objects that interact with one another. But also, from same wikipedia page: >Attempts to find a consensus definition or theory behind objects have not proven very successful (however, see Abadi & Cardelli, A Theory of Objects[68] for formal definitions of many OOP concepts and constructs), and often diverge widely. For example, some definitions focus on mental activities, and some on program structuring. https://en.wikipedia.org/wiki/Object-oriented_programming But I also recommend reading the chapter on objects from "Programming Languages: Application and Interpretation" by Shriram Krishnamurthi.

"Objects — the bundling of data with operations over them — are a generalization of closures." |
