Redux

Redux is used to change the state of application.

Three principles of Redux

1. Single source of truth - State of whole application is stored in a single tree
2. State is read only - Only by emitting action, we can change the state of applcation
3. Changes are made with pure functions - Reducers which are pure functions can only change the state

Connect

mapDispatchToProps

• It's a method you provide to connect
• Recieves dispatch as an argument
• Allows you to create functions which dispatch actions
• It can return an object which is passed to component as props.
