Part 19 - Optimize using Redux Toolkit, useEffect, useSelector, react-router-dom, and Redux Persist⚡
This is Part 1 of our Q&A-style deep dive into Optimization, Performance, and Scalability in React applications. 👋
In this video, we revisit essential tools and techniques we've already implemented — like Redux Toolkit, useEffect, useSelector, react-router-dom, and Redux Persist — to understand how and why they improve app performance and user experience.
🎬 This is Part 19 of the full series, and the first episode of our new Q&A mini-series.
👉 Subscribe and turn on notifications so you don’t miss Part 2, where we’ll cover advanced strategies like useMemo, caching, lazy-loading, and suspense.
