Free online courseReact Basic Hooks

Course Description

React Hooks changed the way modern React applications are built, making it possible to write clean, reusable logic in functional components without relying on class-based patterns. In this course, you will gain a practical foundation in the basic Hooks that power most real-world interfaces, so you can move from simple components to interactive experiences with confidence.

You will start by understanding what Hooks are and why they matter, then quickly move into state management with useState. You will learn how to update values correctly, avoid common pitfalls when the next value depends on the previous one, and handle more complex scenarios like storing objects and arrays in state. These details are essential for building forms, counters, lists, and UI interactions that stay predictable as your app grows.

Next, you will work with side effects using useEffect, the Hook that helps you coordinate rendering with tasks such as timers, subscriptions, and data loading. You will learn when effects run, how to make them run only under specific conditions, and how to run them just once when needed. You will also understand cleanup functions to prevent memory leaks and unexpected behavior, especially when dealing with intervals or listeners.

A big part of modern web development is fetching data from APIs, and this course guides you through fetching patterns with useEffect. You will see how dependency choices impact re-renders, how to load data once, how to request a single resource by ID, and how to trigger requests intentionally, such as only after a button click. By the end, you will not only know what to write, but also why it works, which helps you debug faster and build more robust React features.

Designed for beginners in web development and for developers transitioning into React, this free online course is a solid step toward building job-ready front-end skills and creating responsive, data-driven interfaces.
