In this course, you will learn to build a fully-functional application with Rails Webpacker, Webpack, and TypeScript.

To kick things off, you’ll walk through the basics of getting Rails set up to use Webpacker which will serve JavaScript and CSS to the browser. You’ll then get acquainted with Stimulus and React which will help with creating richer interactions.

In the latter half, you’ll work with TypeScript and set up communication between a server. Beyond that, you’ll work through managing state in your Stimulus code, as well as how to test and troubleshoot your application.

By the end of this course, you will be well equipped to create larger, more complex applications that make use of modern tools.

Modern Front-end Development for Rails

`export const itemStore = createStore(itemReducer)`

`export const itemReducer = createStore(itemStore)`

Assume that you have a reducer called `itemReducer`. Which of the following is the right way to create a store for it?



Assume that you have a reducer called <code>itemReducer</code>. Which of the following is the right way to create a store for it?

Redux requires its reducers to be able to initialize themselves without any input.

Redux requires its reducers to be able to initialize themselves without any input.

It allows us to create pure functions for state management.

It enables asynchronous actions, which is something that vanilla Redux is not equipped for.  

What is the Redux Thunk library for?

Why is it important to be able to pass functions instead of objects to `dispatch()`?

Why is it important to be able to pass functions instead of objects to <code>dispatch()</code>?
