Conclusion and Summary

The primary take-aways from this chapter of the course.

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.
