Managing React State
This course will teach you how to implement many types of React state including local, global, refs, context, derived, and more. You'll learn how to choose between types of state, how to derive state, and how to share state between components.
What you'll learn
There are many types of state. In this course, Managing React State, you’ll learn how to effectively declare state to create rich, interactive React apps. First, you’ll discover eight ways to handle state in React apps. Next, you’ll explore how to manage each of these types of states including route state, component state, and refs in both function and class components. Finally, you’ll learn when to consider global state via context and third party state libraries. When you’ve finished this course, you’ll have the skills to build complex, interactive React apps in the real world.
