Redux

Question 1

Store

Answer 1

This holds the whole state (all your data) for your app. It is an object with a few methods on it.

Question 2

Actions

Answer 2

Payloads of information that send data from your application to your store. They are the only source of information for the store.

Question 3

Reducers

Answer 3

Specify how the application’s state changes in response in response to an action

Question 4

Provider

Answer 4

From react-redux. We wrap our app in this, and pass “store” to it as a prop.

Question 5

Action Creators

Answer 5

Functions that return actions

Question 6

Dispatching

Answer 6

Synchronously sending an action to the store’s reducer, along with the previous state returned by the store, to calculate a new state.

Question 7

Thunk

Answer 7

Allows you to write action creators that return a function instead of an action. It can be used to delay the dispatch. Makes asynchronous stuff easier to work with.

Question 8

getState()

Answer 8

Store method that returns the current state tree of your application.

Question 9

dispatch(action)

Answer 9

Store method that dispatches an action. This is the only way to trigger a state change.

Question 10

subscribe(listener)

Answer 10

Store method that adds a change listener. It will be called any time an action is dispatched, and some part of the state tree may potentially have changed.

Question 11

combineReducers()

Answer 11

Store helps combine the difference pieces of React that we separated for organizational reasons.
