The key distinction is that with the first approach, handleChange really ought to be a useCallback with input as a dependency, but with the function approach it is not necessary.
I’m not sure that several useStates is better, actually. How about a useReducer instead?

Yeah, an object is probably not ideal for
useState, but you can optimize it by passing a function. Instead of doing this...setInput({...input, [name]: value})...you can do this:
setInput((prevState) => ({...prevState, [name]: value}))The key distinction is that with the first approach,
