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.
