What Hacker News says?
omg, so much negativity here... you should read the previous articles from the author, eg. https://jrsinclair.com/articles/2022/javascript-function-com... then https://jrsinclair.com/articles/2022/what-if-the-team-hates-... it would address some of the concerns and critiques ppl had on this topic here.

HN discussionEnums are Sum Types, which are a type of ADT[1]. Tuples are a Product Types, which are another type of ADT[2]; Sum Types are so called because when you add one to that, you add just one more possibility (It could be A,B now it can be A,B,C). Product Types, on the other hand, give out possibilities based on their Product, so if you add a new property, you multiply it (A,B can both be two things, so you have 4 possibi…

HN discussionI dont disagree - where things like either, maybe or result really shine is when its baked into the stdlib _and_ there is machinery built into the language to make using them easy (like pattern matching, and them being in scope by default). I have used and written several libraries trying to make them work in js/ts and while they are beneficial around my custom domain specific code, you still spend a bunch of time w…

HN discussionDefinitely, I think I wrote imprecisely when I used "humanity". I meant more like I personally wrote it, the sentence structure and grammar are mine, the mistakes are mine, and hopefully it's still clear and easy to understand. Speaking of mixing technical text and style/prose, I feel this link from yesterday did a great job executing both (granted it is an article, not a paper): https://jrsinclair.com/articles/2025…

HN discussionThe author has also written a book which I’ve read a couple of times and enjoyed. A Skeptic’s Guide To Functional Programming With JavaScript https://jrsinclair.com/skeptics-guide I’d recommend it for functional-curious JS devs like myself.

HN discussionI kind of agree with your comment here and with what mlinhares responded with. There are a few engineers I enjoy following who give good, and actionable advice. One is Scott Wvlaschin especially if you're interested in Functional Programming Another is James Sinclair[0]. A couple other names, Ryan Florence and Michael Jackson (the dev, not the singer). And one last one is Kent Dodds. These are mostly people on the f…

HN discussionMore of a comment on the author, I've found his other articles enlightening, useful as both introductions to functional programming ideas and as comprehensive deep dives demonstrating their intuitive nature both in code and contextual application. A lot of the articles in conjunction with some other resources[1][2][3] are great for diving into functional programming (I've watched and read these many times). If you d…

HN discussionI really like https://jrsinclair.com/web-development/ . The author writes in a very easy to understand way. The subjects are always interesting and more unique. The author isn't writing, like everyone else, about the newest version of React or Typescript. There is depth to each post. Lots of code examples and lots of simple explanations of complex ideas. The tone is casual, like a conversation, rather than a lecture…
