Optimizing React with useState, useEffect, useCallback, useMemo, and useRef | Day 64

In this session of our Web Development Series, we dive into the core React hooks: useState, useEffect, useCallback, useMemo, and useRef. These hooks are essential for managing state, side effects, performance optimization, and references in functional components.

What we’ll cover:

useState: Learn how to manage local state in a functional component and understand best practices to avoid unnecessary re-renders.
useEffect: Understand how to perform side effects like data fetching, subscriptions, and DOM manipulations, and how to optimize it with the dependency array.
useCallback: Explore how to memoize callback functions to prevent unnecessary re-creations on re-renders, helping in performance-sensitive scenarios.
useMemo: Discover how to memoize expensive calculations or values that don’t need to be recomputed on every render, boosting app performance.
useRef: Get familiar with using refs to persist values across renders, manage DOM elements, and avoid re-renders when updating mutable values.
This video will guide you through real-world examples and best practices to ensure your React app remains optimized and performant as it grows.
