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

Context

Starting the Project

React in the Real World Section Sum Up

Follow these steps to develop a React app on your local machine:

Install Node.js and npm:

Visit the official Node.js website at https://nodejs.org;
Download the installer for your operating system and follow the installation instructions to install Node.js and npm.

Install a Code Editor:

Choose a code editor that suits your preference, such as Visual Studio Code;
Install the code editor on your computer;
This code editor will be your tool for writing React code.

Create a Project Folder:

Create an empty folder on your computer to store your React project;
This folder will serve as the root directory for your project.

Open the Code Editor:

Launch the code editor of your choice;
Navigate to the project folder you created in step 3;
This will allow you to start working on your React project within the code editor.

Open the Terminal:

Within the code editor, open the terminal or command line interface;
This is where you'll run commands to set up and manage your React project.

Set Up the Project:

In the terminal, run the command npx create-react-app .;
This command initializes a new React project using the Create React App tool.

Start the Live Page:

Run the command npm start once the project is created;
This starts the development server and opens a live preview of your React app in the browser.

Customize the Project:

Open the src folder within your project directory;
You can delete all default files created by Create React App;
Build your React components, add styles, and implement functionality within the src folder.

Happy Coding!

Following these steps, you'll have a basic React project set up and ready for development. You can now start building your React components, styling your app, and adding functionality as needed for your project.
