We've now arrived at Day 5 of our special 6-part YouTube tutorial series on React Hooks . Hooks are so important for all React developers to understand because, conceptually, React components have always been closer to functions and the library supports a functional way of thinking. Hooks add powerful capabilities to functional components. Now in Tutorial 5, Paige covers a powerful Hook - the useContext Hook: The use of component hierarchies solved problems in React around composing UI out of smaller individual parts, but created a range of new problems:

We are continuing the tutorial series on React Hooks . Join Paige in today's tutorial as she teaches you all about the useRef hook, how it works, and how to use it in your own React apps. React refs help you imperatively modify the DOM outside the normal flow of component rendering. Here are some example scenarios: Since refs have often been thought of as an escape hatch that indicates that state should be managed elsewhere in the component hierarchy, there are a lot of questions about how to use them correctly. In this detailed but beginner-friendly guide, Paige goes over the nuances of using refs and the useRef React Hook properly so that you can confidently manage DOM elements directly in React.

We have the third tutorial in our 6 part YouTube series on React Hooks. (ICYMI - You can check out Part 1 - Introducing Hooks and Part 2 - useState Hook ). Now we're on to the useEffect hook, an incredibly useful hook that allows you to handle side effects such as API calls or modifying the DOM in your function components. The useEffect Hook performs side-effects in function components. The term "side-effects" refers to actions that cause things to occur outside the scope of the function being executed. This includes sending requests to an API, logging, modifying the DOM, subscribing to event listeners, etc. Behavior-wise, you can think of the useEffect Hook as the componentDidMount , componentDidUpdate , and componentWillUnmount lifecycle methods you'd use in class-based components, neatly packaged into one Hook. Follow along as Paige teaches you this second of the most important React Hooks you should know.

Here is the second tutorial in our 6 part YouTube series on React Hooks. We've already seen that React Hooks are arguably the biggest fundamental change to happen to React since its inception. Learning Hooks brings you up to speed with this important update to React. Now in this second tutorial, we will teach you the ins and outs of using the useState hook, the most commonly used React Hook, and thus, one of the most important ones you should know. You will see that state management using the useState hook is in many cases more straightforward than using class-based components. Function components have come a long way since React v0.14. Introduced as a simpler syntax for defining stateless, presentational components, function components can now handle state via the useState Hook.

In this course, we’ll build a set of custom reusable hooks, a mini react-hanger clone, essentially going from nothing to a fully-automated publishing pipeline that follows the best practices. We cover common Hooks APIs every React developer should know, then dive straight into implementing Custom React Hooks, similar to what you will find in leading React libraries in the open source React ecosystem. Course modules include:
