When documentation writers decide to write a 200-word essay about the "second argument of the setState() function" instead of just calling it what it literally is: a callback. You know, that thing developers have been calling callbacks since the dawn of asynchronous programming?
The React docs are out here writing thesis statements about "powerful mechanisms for handling state updates and executing code after the state has been updated and the component has re-rendered" when they could've just said "callback function runs after state updates." That's it. Three words. Done.
The frustration is real because this verbose documentation style makes you feel like you're reading a legal contract when you just want to know what parameter goes where. Sometimes simplicity beats eloquence, especially when you're debugging at 2 AM.
