Data Oriented Programming. In short, don't entangle your code with data, and the data should immutable. https://blog.klipse.tech/databook/2020/09/25/data-book-chap0...

HN discussionI think ClojureScript has been able to compile itself since ~2015 if I remember correctly. There is some helper libraries that makes the experience nicer nowadays too, tools like KLIPSE ( https://github.com/viebel/klipse ) Here are some starting points: - https://clojurescript.org/guides/self-hosting - https://practicalli.github.io/clojurescript/quickstart/self-... - https://blog.klipse.tech/clojurescript/2016/04/04…

HN discussionI understand your worry, but I've had a quite opposite take on this. I think we can agree that it's not that hard to find ANY job as an experienced developer. However it's much more difficult to find a great, satisfying job. For that you need to navigate around a lot of corpo-bullshit type of projects, and Clojure has served me well as a useful filter in doing that. My reasoning is that Clojure is niche enough that…

HN discussion> I can't get past the lack of currying. Say again? Currying may not exist as a special form, but adding it is utterly trivial: [0] Which I guess is where Lisp shines. Modifying the language to suit your needs is easy. You aren't bound by the limits that many languages force upon you. That being said, I wouldn't say that Common Lisp or Ocaml have the same userbase. In much the same way that C and JavaScript don't se…

HN discussionAwful stuff. These principles could only ever make sense in a dynamic language since it's mostly manually enforcing some of the basic functionality of a type system, but the fact that he also tries to argue this style could be used in a language like C# throws that defense out the window. https://blog.klipse.tech/databook/2022/06/22/generic-data-st...

HN discussionIts official use case is hacking recursion into a language that doesn't support recursion, but does have first-class functions. To the best of my knowledge, the only language that fits this description is the lambda calculus itself. There is a paper, Y in Practical Programs ( https://blog.klipse.tech/assets/y-in-practical-programs.pdf ) that presents some interesting things you can layer on top of the technique. I'l…

HN discussionFor most things, yes. But this is JavaScript, the language where intransitive equality, implicit object-to-primitive casting and mutable global objects must be used in all slight-above-trivial code. Where `typeof` is useless and wrong, but nonetheless necessary; where there are seven different ways to parse a number, with six different semantics… there's a reason that “JavaScript: The Good Parts” is such a short boo…

HN discussionYour small dive prompted me to create a simple version of what you were describing [1]. I didn't use my usual editor, and just used the cljsfiddle itself. I really wanted to create a spec for the data in app-state, and check the value in the app-state atom each time I edited it (perhaps with an add-watch). That gets you many of the same advantages of static typing, but you only add the extra insurance when you think…
