Part 2: Basic Approaches to the Global State

There are several approaches to using the global state effectively in React. Our focus is on optimizing re-renders. This is important because a global state can be used by multiple components. We describe three patterns – using Context, using Subscription, and using both Context and Subscription. We discuss how those patterns address the optimizing of re-renders.

This part comprises the following chapters:

• Chapter 2, Using Local and Global States
• Chapter 3, Sharing Component State with Context
• Chapter 4, Sharing Module State with Subscription
• Chapter 5, Sharing Component State with Context and Subscription
