I'm unsure if anybody mentioned this yet, and I don't know where to open this discussion, but Future and async/await aren't a good programming model, and I hope that, for whatever new e...

Out of the Alt-JS languages I've played with, Scala.js seems to be the best. Given it's probably not widely adopted, its maturity is surprising. E.g., ScalablyTyped can convert TypeScript definitions, and actually works. Interop is good. And the compiler is, dare I say it,

Ironically, #TypeScript seems to get ahead in its support for monadic effect systems. This is `Effect`, a ZIO-inspired library, making use of JS's generators:

The Generator object is returned by a generator function and it conforms to both the iterable protocol and the iterator protocol.

@sivalabs @antonarhipov When people get interested in FP, there are usually good reasons, usually having to do with managing complexity. Most know how to “get shit done”, and if that's the benchmark, then FP is screwed, as getting shit done (at least for demonstration purposes) is easier w/ imperative

"Impure" functions in an FP context have negative value because impurity violates the contract of the underlying abstractions, making them leaky, so you end up working with a minefield...

In software, if we were to classify the methodologies doing the most damage to our practice, “aspect-oriented programming” is definitely in the Top 3. The consequence of an OOP language that rejected HOFs for 2 decades, and that shall remain anonymous.

@graninas By OOP, we understand subtyping polymorphism / dynamic dispatch, which drives encapsulation as a goal, and a trait that OO excels at. Other people understand by OO working w/ objects that have identity (state), so they complain about imperative programming or the design patterns

FP languages rock! Here's what #Scala 3 would roughly look like (making use of @Typelevel 's Cats & Cats-Effect). As a comparison, I love #Fsharp 's Hindley-Milner type inference. OTOH, this Scala uses code more generic, e.g., `foldM` vs `foldAsync` and no need of `AsyncSeq`.

This is one of my favourite pieces of code I've written in a while. Doing this sort of recursive async work to apply transformations on a file tend to be quite messy in other languages I've tried #fsharp code is just love. #dotnet

New #programming languages aren't worth learning if they don't broaden the horizon of things you can do, like embracing new paradigms for managing complexity, targeting other platforms, building other types of apps. Also, the incumbents are here to stay.

@deusaquilus @Java_Champions Java will never be good for FP. The language has been decent enough since Java 8, and a cultural shift began to happen alongside the adoption of reactive APIs (spearheaded by RxJava). However, there has always been a resistance to it, and Project Loom has signaled that shift to

In Scala 3, use 4 Spaces for Indentation

Scala’s coding style advised to use 2 spaces of indentation, but that was before Scala 3’s optional braces, which introduces significant indentation. It’s time for an upgrade of the coding style.

@ThePrimeagen @BenLesh It's not a bug because Promise.then, in JavaScript, does auto-flattening. So returning a Promise from an async function will auto-flatten that Promise. I.e., working with a Promise<Promise<A>> isn't really possible. Note that people objected to this behaviour when it was
