Conclusion and Summary

This chapter has been exciting. We focused mostly on setting a decent foundation for the more interesting things to come.

Here are a few things you learned in this chapter:

• Redux is a predictable state container for JavaScript apps.
• The createStore factory function from Redux is used to create a Redux STORE.
• The Reducer is the only mandatory argument passed into createStore().
• A REDUCER is just a function. A function that takes in two parameters. The first being the STATE of the app, and the other being an ACTION.
• A Reducer always returns the NEW STATE of your application.
• The INITIAL STATE of your application, initialState is the second argument passed into the createStore function call.
• Store.getState() will return the current state of your application, where store is a valid Redux STORE.
