What is the first step in managing state for a product list?

• Importing a reducer

• Setting up a database

• Writing a CSS file

• Creating a new component

Why is useReducer preferred over useState for complex state logic?

• It handles complex state logic better

• It requires less code

• It is easier to write

• It is faster

What happens when a dispatch is called in the context of state management?

• The state is reset

• The state is updated

• The state is deleted

• The state is logged

What is the purpose of the initialize function in the context of a product list?

• To initialize the product list with data

• To filter the product list

• To delete the product list

• To sort the product list

What is the significance of the payload in a dispatch function?

• It contains the reducer function

• It contains the new state

• It contains the data to update the state

• It contains the action type

How is the product list updated with data from an API?

• By using a for loop

• By calling a setTimeout function

• By using a dispatch function

• By directly modifying the state

How does the reducer function contribute to state management?

• It initializes the state

• It logs the state changes

• It returns the updated state

• It deletes the state

What role does the global state play in managing the product list?

• It stores temporary data

• It is used for debugging

• It acts as a local storage

• It provides a centralized storage for the product list

What is the effect of applying a filter on the product list?

• It sorts the list alphabetically

• It updates the list to show only filtered items

• It clears the list

• It duplicates the list

Why might a warning appear regarding the initial product list?

• Because it is not a function

• Because it is not used

• Because it is missing in the dependency array
