This article is an excerpt from my book about Data-Oriented Programming.

More excerpts are available on my blog.


This chapter is an attempt to illustrate what are the core principles of Data Oriented Programming as I understand them. It is highly influenced by my programming experience in Clojure, but I believe that those principles are language agnostic.

One could adhere to them in an Object Oriented (OO) language like Java or C# and one could break them in a Functional Programming (FP) language like Ocaml, Haskell, JavaScript (or even in Clojure).

In fact, in this chapter, I am going to illustrate how those principles could be applied or broken in JavaScript, a programming language that supports both FP and OOP.

The principles of Data Oriented (DO) Programming are:

  1. Separate code from data

  2. Model entities with generic data structures

  3. Data is immutable

  4. Data is comparable by value

  5. Data has a literal representation

Each principle is explored in a separate article.

I encourage you to start your exploration from Principle #1: Separate code from data.

Enjoy!
