How To Write Custom React Hooks
Writing custom React hooks involves encapsulating stateful logic and functionality into reusable functions that can be shared across multiple components. To create a custom hook, you start by defining a function that begins with the prefix "use" (for example, `useFetch` or `useForm`). Inside this function, you can utilize built-in hooks like `useState`, `useEffect`, or others to manage state and side effects. The custom hook can then return any values or functions necessary for managing the logic. This modular approach not only promotes code reusability but also simplifies complex components by separating concerns, making your codebase more organized and maintainable.
How To Write Custom React Hooks
Writing custom React hooks is a powerful way to encapsulate and reuse stateful logic across your components. By creating a custom hook, you can abstract complex functionalities—like data fetching, form handling, or local storage management—into a single, manageable function that can be shared throughout your application. This not only promotes cleaner and more modular code but also enhances maintainability, as updates to the logic only need to be made in one place. Custom hooks foster a better separation of concerns, allowing you to keep your components focused on rendering while the hooks handle the underlying functionality, ultimately leading to a more efficient development process.

The course focuses on functional components, allowing students to rejuvenate their coding practices while adhering to React’s best practices.
2) JavaScript (ES6+)
A firm understanding of modern JavaScript (ES6 and beyond) is essential for this course, as students will utilize features such as arrow functions, destructuring, and async/await. The course content will encourage developers to leverage these features when writing custom hooks, enhancing readability and maintainability. The emphasis on ES6+ syntax ensures that participants are well prepared to work in contemporary environments.
3) Code Editors/IDEs
Students will use various code editors and Integrated Development Environments (IDEs) such as Visual Studio Code or Atom. The course encourages the installation of relevant extensions and tools that aid in React development, such as ESLint for code quality, Prettier for code formatting, and React Developer Tools for debugging. Familiarity with these tools will enhance developers' efficiency and coding experience while promoting best practices in development.
4) NPM and Yarn
Package managers like NPM and Yarn are integral to managing project dependencies throughout the course. Students will learn how to set up React projects, install various libraries, and manage updates using these tools. Understanding package management ensures students can efficiently carry out their projects and easily incorporate external libraries that enhance functionality, such as Axios for API calls or Lodash for utility functions.
5) Git and Version Control
