Introduction to Redux — State, Actions, and Reducers

Redux replaces scattered component state with a single immutable state tree updated only through pure reducer functions. After this lesson you can define a Redux state shape, write action objects with correct payload data, implement the color and colors reducers using pure functions and immutable updates, and explain the complete data flow from dispatch to new state.
