relevants

Please point me to where I said that then. Given that my stance is just that it's not very plausible, I would be very interested to see where I supposedly claimed it wasn't possible.

How are you saying you "straight up disagree" and then you go on to agree with me that for someone without exceptional experience, 5-6 days is reasonable?

I think there's a pretty significant difference between a week and 2 days in terms of how much time you had to solidify your understanding.

I also didn't take that long to pick up the basics, but I could not say that I understood hooks within the first two days of working with React. There are just so many small details and limitations that can catch you by surprise if you don't know why hooks work the way they do, same with the lifecycle of a component and what triggers a re-render. That does take a few days to fully understand in a way that you can utilize moving forward.

It's possible that I had a harder time because I was used to manipulating the DOM directly, and so managing all updates through state changes and being strongly discouraged from directly referencing UI elements felt very foreign to me. I don't think that my stance would change if I had a different experience in the beginning though.

Glossing over the pretentiousness of your comment

And your stance of "I can learn x in two days, so how can people say it takes longer to learn y" isn't pretentious?

When do you consider someone's "mental model" "appropriate"?

"appropriate" isn't a quantification of the mental model in itself, I am using the word as "having a mental model that is appropriate to the thing being learned". A different mental model is required for React than working with vanilla JS and manipulating the DOM directly, so the mental model for one isn't appropriate for the other.

And yes, a mental model is quantifiable, to the extent that it accurately predicts what consequences design and implementation decisions may have on the behavior of the system.

How do you know what is similar in complexity to React? As far as I can tell you aren't familiar with it.

at least at a base level while you google how to do everything else

Ah, there's the problem. Your definition of learning doesn't include having an appropriate mental model, which is key to actually retaining and internalizing the way it works. I don't think it's unreasonable to say that is a prerequisite for claiming to have "learned" something like a language or framework.

React, Vue, Solid, ... are a lot more complex than your average JavaScript library, because they contain so many abstractions and basically require a separate "way of thinking" in addition to what you know from JS itself. There's a separate state and UI model, hooks are a foreign concept at first, and component memoization and re-rendering takes some getting used to as well.

Now, I only have two years of experience with React, but ten in JavaScript overall, and I will say that using React/JSX required the biggest "mental model shift" for me. That's not to say that it's difficult to work with or particularly hard to learn, but it takes time to understand and really internalize this language-within-a-language library.

The way you're asking that question seems to imply that because the API of some Python libraries can be learned in two days, the same must be possible for React, and that seems rather dismissive.

Students - all non-wage-earners - shouldn't be able to vote by your logic?

I don't know how you could possibly derive that conclusion from what they said, unless you lack a very basic understanding of how to interpret logical statements.

Ah man, I've been playing various Trackmania titles since 2013 but I still struggle with some of the campaign author medals and my placements are only around top 5-10% of players. Better than average sure, but not "exponentially" [sic] despite years of experience :(

Lol und ich dachte erst das war vielleicht wirklich Zufall, aber als ich dann im Schaufenster das "Big Döner Energy" und "Get Stuffed" sah war klar dass der Laden sich das schon genau so als Marke ausgesucht hat.

Then you did a very poor job of making that point through your (presumably rhetorical) question.

Setting aside how needlessly passive-aggressive your comment is– most people don't care about the world at large. They care about their family, their social circle, their tribe/in-group, but not the world at large. Otherwise climate change wouldn't be as big of an issue in the first place.

For a second I thought you were calling sea water a dangerous gas.
