3. React Hooks and Context

Powerful features in modern React development. Hooks revolutionize how we write functional components, providing a concise and intuitive way to manage state and perform side effects. Conversely, Context allows us to share data through the component tree without prop drilling. Combining hooks and Context enables efficient state management and simplified data sharing in React applications.

Introduction: React Hooks and Context

useState Hook

Challenge: Toggling Visibility

useRef Hook

Challenge: Creating a Form Component

useEffect Hook

Challenge: Fetching and Displaying Data

useMemo Hook

Challenge: Car List Filtering

Challenge: Rendering a Data Collection

Task: Show a Product List

Let's handle the data obtained from the backend and ensure its proper rendering in a list format.

The task is:

Utilize the map() method to render an array of goods.
Ensure to fill the necessary gaps:
1. h2 must contain the good's name (name property);
2. p must contain the good's description (description property);
3. span must contain the string "Price:" and the good's price (price property).

Use the map() method to map over the props.goods array.
Ensure to set the key prop of the <li> element to a unique value, such as the id property of the item.
Inside each <li> element, use the following elements:
- An <h2> element to display the good's name. Access the name from the current item;
- A <p> element to display the good's description. Access the description from the current item;
- A <span> element to display the string "Price:" followed by the good's price. Access the price from the current item.
