Using React 17 Hooks
React Hooks bring state and lifecycle events to React Functional Components as well as streamlining code that previously was coupled and complex. Learn techniques for using React Hooks including Redux-like state management with React Context.
What you'll learn
React Hooks reduce the complexity associated with managing state and lifecycle events exclusively in React Functional Components. What previously was complex, and often required middleware to implement, can be easily done and extended using React Hooks. They are called “hooks” because they allow the developer to hook into existing pre-built functionality. In this course, Using React 17 Hooks, you'll gain the ability to consume pre-built React Hooks, as well as author your own custom React Hooks. First, you’ll learn all about the six most commonly used React Hooks that are built into the React core library. Then, you’ll see how they compare to the corresponding state and lifecycle events in more traditional legacy React Class Components. Next, you’ll explore how to both consume and author your own re-usable custom React Hooks. Finally, you’ll be shown how to combine React Context with React Hooks state management to integrate a Redux-like state management solution into your React app. When you are finished with this course, you’ll confidently be able to build fully capable functional components that use React Hooks.
