useEffect, useRef and useCallback with 1 project in Reactjs

Complete React course for beginner

In this video, Hitesh walks you through the practical use of ReactJS hooks like useEffect, useRef, and useCallback by building a simple yet insightful project—a password generator. Despite the project’s basic appearance, it’s designed to demonstrate ReactJS best practices, focusing on optimizing component re-rendering and enhancing user experience. Hitesh explains how useEffect runs code on component mount and re-runs when dependencies change, ensuring the password updates dynamically. The useRef hook is utilized to reference and manipulate DOM elements, such as highlighting text when copying. Additionally, useCallback is introduced to optimize performance by caching function definitions, preventing unnecessary re-renders. This project, built using Tailwind CSS for styling, is an excellent example of how even a simple ReactJS application can involve complex, efficient coding techniques. Throughout the video, Hitesh emphasizes the importance of understanding these hooks to write cleaner, more efficient React code, making it a must-watch for anyone looking to deepen their ReactJS knowledge.
