  1. Hey. You should wrap callbacks in useCallback, especially in real apps that become larger. Then, you’ll need to pass current state as dependency into that hook, which makes the approach almost obsolete.
    The solution and important lesson: setState(current => ({…current, …next}))
    Use a function to set the state, and you’ll get the current one for free, without it being a dependency of the callback hook.

  2. let updatedValue = {};
    updatedValue = {“item1″:”juice”};

    why not in one statement :

    let updatedValue = {“Item1″:”juice”}
