Introduction to action & reducers

What is one hacky way to force a UI change in React?

• Maintaining a local state and updating that post dispatch

• Updating the global state

• Using a different component

• Changing the CSS

What is the problem with maintaining a local state to force a re-render in React?

• It's not scalable

• It updates the global state

• It changes the CSS

• It directly updates the DOM

What is one solution to ensure operations are executed after the store gets updated?

• Maintain a set of operations to be executed after the store gets updated

• Execute operations before the store gets updated

• Ignore the store update and proceed with operations

• Execute operations randomly

When should the operations be executed according to the solution?

• Before calling the handler inside the dispatch method

• Right after calling the handler inside the dispatch method

• Before the store gets updated

• Randomly at any time

What can be maintained in the store to push operations on the mount of interested components?

• A list of handlers

• A subscribers array

• A set of operations

• A dispatch method

What does maintaining a subscribers array ensure?

• Only the first component triggers the state update

• The state change will be reflected in sync throughout the application

• Operations are executed randomly

• The state update is ignored

What is the main problem with Prop Drilling?

• It makes the application slower.

• It causes components to receive data they do not need.

• It increases the complexity of the application.

• It prevents the application from updating state.

What prevents the problem of Prop Drilling?

• Local State Management

• Component-based Architecture

• Global State Management

• Event Handling

What is a store in the context of state management?

• Object

• Class

• Function

• Constant

How can the application pass the initial state in state management?

• By using the getState() function.

• By using the dispatch() function.

• By using the createStore() function.

• By using the subscribe() function.
