It's helpful, thank you😁
If you don't mind, could you explain more about the 7th quesiton?
The answer has done with a sentence It works well with React because it allows for predictable flow of data and more consistent behavior., I think there may be posibilities that they ask you why that is predictable flow of data and more consistent behavior.
I'd like to know what your answer of the question is.

Hey @lico , thanks for connecting on LinkedIn!
What I meant is that Redux works fluently with React by keeping things simple and predictable. Instead of having little pockets of state hidden in different components, Redux places all state in one global store. This way, any component can reach in and grab the state it needs, without having to pass props around through components.

Redux also sets down strict rules for changing state. You can't just tweak state directly; instead, you have to dispatch an action - a plain instruction of what should change. Then a reducer (a pure function, mind you) takes the current state and action, and spits out the new state.

With this flow, you've got a clear trail of what state changes occurred and why. It's like having a trail of breadcrumbs leading up to the current state. This makes debugging a LOT less of a headache and helps keep your app's behavior consistent. That's why I say Redux allows for predictable data flow and consistent behavior. Hope this helps!
