This course is a beginner's gateway into the mechanics of using Redux as an application building platform. It takes a bottom-up approach, enforcing the basic aspects of Redux before incorporating them together in a creative and interactive way. It begins with a short theoretical section before moving on to application based problems. 
The course does assume that the user has a basic idea of how React works, as Redux works in the React environment. Let's dive in!

Understanding Redux: A Beginner's Guide To State Management

As we observed in the previous lesson, sending a message returned only an empty string and hence, erased all the contents of the conversation:

Keep in mind that every user has an array of 10 messages. When retaining a user's conversation, we only need to obtain the array for that specific user. Also, we will be adding new messages to the array. How do we iterate through the messages? Lodash to the rescue. This will all be implemented in the message reducer.
