I'm Max Stoiber (@mxstbr) - the creator of react-boilerplate, one of the most popular react starter kits (10K+ stars on github).

I'll teach you how to build a real-world application using React, Redux and Immutable.js. We will use interactive playgrounds to create our app from scratch (no setup required).

The course can be divided into 4 logical parts: 

1. React: Understand what is React and what problem it solves. We'll build our first weather app using just React.
2. Redux: Identify potential issues in our React app and learn how Redux & Redux-Thunk can solve those issues. 
3. Immutable.js: Learn Immutable.js and how it can help in making our Redux apps performant. 
4. Jest: Lastly, we will learn how to test our React/Redux app using Jest.

If you are going to build a production app, chances are that you are going to use all of the above technologies so let's get started. 

* Understanding of Javascript is required. 
** Understanding of ES6 (let/const, arrow functions etc.) would be beneficial.

Learn React.js, Redux & Immutable.js while building a weather app

Immutable data structures can't be changed. So when we convert a regular JavaScript object with `fromJS` what ImmutableJS does is loop over every single property and value in the object (including nested objects and arrays) and transfers it to a new, immutable one. (the same thing applies in the other direction for `toJS`)

The problem with standard JavaScript objects is that they have `reference equality`. That means even when two objects have the same content, they're not the same:

In this lesson, we'll take a quick look at the internals of ImmutableJS so that we have a better understanding of how can we apply Immutable.js to our Redux app in a performant manner.
