Ramda: A practical functional library for JavaScript programmers
Personally I just don't think Ramda fits really well with JavaScript's mutable and often object-oriented nature. It goes against the grain too much for my taste, and it doesn't work very well with Typescript.
In a professional setting I will probably always reach for Lodash due to it's maturity and mindshare. Personally, though, I really prefer Remeda (https://github.com/remeda/remeda) as a pragmatic and flexible API.

Avoiding legacy systems
The good news is: Not all is lost. The messages are still there if you take a look at the commits of the PR. It's just a little harder to backtrack. Here is one example of a commit I made that has tons of information (even with a link!) that got squashed away.

Functional Programming 1
2. https://github.com/fantasyland/fantasy-land (A bit heavy on jargon)
Note there is a python version of Ramda available on pypi and there’s a lot of FP tidbits inside JAX:
3. https://pypi.org/project/ramda/ (Worth making your own version if you want to learn, though)
4. For nested data, JAX tree_util is epic: https://jax.readthedocs.io/en/latest/jax.tree_util.html and also their curry implementation is funny: https://github.com/google/jax/blob/4ac2bdc2b1d71ec0010412a32...
Anyway don’t put FP on a pedestal, main thing is to focus on the core principles of avoiding external mutation and making helper functions. Doesn’t always work because some languages like Rust don’t have legit support for currying (afaik in 2023 August), but in those cases you can hack it with builder methods to an extent.
Finally, if you want to understand the middle of the midwit meme, check out this wiki article and connect the free monoid to the Kleene star (0 or more copies of your pattern) and Kleene plus (1 or more copies of your pattern). Those are also in regex so it can help you remember the regex symbols. https://en.wikipedia.org/wiki/Free_monoid?wprov=sfti1
The simplest example might be {0}^* in which case
0: “” // because we use *

Ramda: A practical functional library for JavaScript programmers
It was never really my jam, but I used to follow the up-and-coming fantasy-land specs with great interest. It just seemed like a sharp dedicated community of folks trying to figure out better fp & algebraic stuff. I'm not sure who trailed off - in general I feel like there's much less connection in tech world, that the tech twitter and every other ultra-active tech channel has somewhat decayed. https://github.com/fantasyland/fantasy-land
Thanks for the links. I know I've seen @gcanti's name a thousand times already, but it's already quite murky to me what it was attached to. Something in this sphere.

I came across the "Fantasy Land Specification", it somewhat conflicts with my own simplistic understanding of monads and functors. Is this specification valid, and should I honor it?
While building a purely functional data structure library for personal fun and professional use, and while using other libraries, I found that the "Fantasy Land Specification" was mentioned from time to time. They use this hierarchy. Although I did read some about category theory (tried and failed to fully understand all the concepts), some of the terms used in the specification are unknown to me (like Chain, Apply). My question:
-
Best explanation of monads ive ever seen, from the practical developper’s point of view.
No: neither of those examples are "properties of futures and of lists as such." "Async/Await" in particular is a special case of monadic behavior of a concurrency monad. This specifically (infamously) came up in the evolution of the Prommise spec in ECMAScript, which in turn led to the development of the Fantasy Land Spec and various implementations of it.
- should i learn design patterns?

Design Patterns Book for functional programming?
If you're programming in TypeScript you can checkout the fantasy land spec. It provides a spec for all the algebraic structures used in the JS world. You can learn what they are. You'll want to find alternative resources to learn what they are how they work. Fantasy land is just a spec not a guide.
