Course Description

React Basic Hooks by App Dev is a free online course in Technology and Programming, designed for web development learners who want to understand how modern React components manage state and side effects.

You will build a clear foundation in Hooks, starting with the basics and moving into practical patterns for everyday development. The course walks through using useState in multiple scenarios, including updating based on previous values and working with complex data such as objects and arrays.

It also explains useEffect in depth, helping you reason about what happens after render, when effects should run, and how to control them with conditions and dependencies. You will learn how to run effects only once, how to create cleanup logic to prevent issues, and how to avoid common mistakes related to dependency arrays.

To connect these concepts to real-world work, the course demonstrates data fetching with useEffect, helping you understand how to structure asynchronous logic and keep components predictable. By the end, you will be better prepared to write cleaner React code, reduce bugs caused by side effects, and confidently apply Hooks in your own projects.
