⚡ ReactJS Virtual DOM: The Secret Behind Blazing-Fast UI 🚀
⚡ ReactJS Virtual DOM: The Secret Behind Blazing-Fast UI 🚀 When you hear ReactJS , the first thing developers admire is its speed and efficiency . But have you ever wondered how React achieves this? 🤔 The magic lies in the Virtual DOM (VDOM) — a concept that makes UI rendering super-fast and efficient. In this blog, let’s deep dive into: ✅ What is Virtual DOM? ✅ How it works step by step ✅ Key features of Virtual DOM ✅ Tools & techniques around it ✅ Best tricks to master it 🌱 What is the Virtual DOM?
