however, since you know Haskell, i do find it pedantic from your side that you're attaching to the "useState makes it impure" position when clearly useState() API could have been made monadic in the way i wrote above without any changes to the actual thing it's expressing. so it doesn't matter

but yes, i'm not saying React is actually pure in the Haskell sense. that would be absurd. it's written in JavaScript which has an entirely different model. i thought this would be clear enough to a reader who knows both, and they'd be able to infer what i'm trying to say from the paragraphs below

since React conceptual model maps 1:1 to what i'm describing above, which *is* pure, we should be able to talk about React in those terms if we want to. otherwise it wouldn't be a 1:1 mapping. yes, the actual way React works is different, but that's a different pragmatic encoding of the same model

it isn't impossible, it's just clunky to write in JS because it has no `do` notation (`await` is limited to Promises, and `yield` would screw up static typing). it's also unnecessary runtime overhead to create intermediate closures that's why React just does useState(). "use" is the "do"

it could look similar to chaining Promises, like function Counter() { return useState(0) .then((count, setCount) => { return useEffect(() => { // ... }, [count]).then(() => { return <div>{count}</div> }) }) entirely pure, just a chain of continuations

time for an

my name is Andre, I'm a software engineer from Brazil, working mostly with Ruby nowadays, but I'm also Rust-curious.

I was recently diagnosed as being on the spectrum. I'm married, I have a daughter, and, probably, too many cats.

I guess my main hobbies nowadays are reading and listening to heavy metal.

Is your WhatsApp really private?

Short answer: Of course not.

Although WhatsApp uses end-to-end encryption to protect the content of messages, it collects a large amount of metadata and personal information that can reveal much more about you.

Find out here.

The information that WhatsApp collects can be grouped into several categories, according to its own privacy policy.

However, the most valuable information is extracted from metadata, Meta's gold mine.
