advantage of immutability in Redux?

Redux architecture revolves around a strict unidirectional data flow.

Data lifecycle: 1. You call store.dispatch(action) 2. Redux store calls the reducer function 3. combine output of multiple reducer into on single state tree 4. Redux store returns the complete state tree (returned by the root reducer)

Ex with a combineReducers() function todos(state = [], action) { // Somehow calculate it... return nextState } ​ function visibleTodoFilter(state = 'SHOW_ALL', action) { // Somehow calculate it... return nextState } ​ let todoApp = combineReducers({ todos, visibleTodoFilter })

React bindings for Redux embrace the idea of separating presentational and container components.

Container Components: How things work (data fetching, state updates) Dispatch Redux actions Are usually generated by React Redux

Presentational Components How things look (markup, styles) Invoke callbacks from props to change data Are written by hand

You could write a container component by hand, but we suggest instead generating container components with the React Redux library's connect() function, which provides many useful optimizations to prevent unnecessary re-renders.

To use connect(), you need to define a special function called mapStateToProps that tells how to transform the current Redux store state into the props you want to pass to a presentational component you are wrapping.

In addition to reading the state, container components can dispatch actions. In a similar fashion, you can define a function called mapDispatchToProps() that receives the dispatch() method and returns callback props that you want to inject into the presentational component.

Connecting react and redux: import { connect } from 'react-redux' ​ const VisibleTodoList = connect( mapStateToProps, mapDispatchToProps )(TodoList) ​ export default VisibleTodoList

Redux component <Provider> : is used to magically make the store available to all container components in the application without passing it explicitly. You only need to use it once when you render the root component:

How do you use <provider> ?

There's a science fiction project we really want to make, but it's very expensive. Hopefully it will happen.

I always keep myself busy. I'm writing. Or I'm creating something. Or I'm doing stuff with the kids. I'm up incredibly early in the morning; I go to bed incredibly late at night.

If you look at casualties, you find countries that had much higher loss rates per capita than the US. Denmark comes to mind, the United Kingdom, they have suffered heavy losses at various points, the Germans as well.

Beauty is the only thing that time cannot harm. Philosophies fall away like sand, creeds follow one another, but what is beautiful is a joy for all seasons, a possession for all eternity.

Opening Ceremony is my number one favorite place to shop here. It's the only place I'll shop in New York with my son. All of the sales people are so cool; the music is great; it's just like a big fun house, so he stays entertained.

Principle says it's not who put forth an idea. It's not the position of the person who put forth an idea; it's not the longevity of the person or the party of the person. That's not what it is at all. In a power system, that's the way it works. But in a principle system, it's what it says.
