React Reconciliation Explained Simply | Virtual DOM & Diffing Algorithm

In this video, I explain *React Reconciliation * in a simple and practical way. We’ll understand how React decides what needs to change when state or props change, and how React efficiently updates the browser DOM. Topics covered: What is React Reconciliation? What is the Virtual DOM? When is the Virtual DOM created? How React compares previous and new UI trees Diffing Algorithm Render Phase Commit Phase How React updates the Real DOM How `setState` / `useState` triggers an update How all these concepts are connected Code Editor OneCompiler – React: https://onecompiler.com/react Whiteboard / Diagrams Excalidraw: https://excalidraw.com/ I'm documenting my journey of learning and understanding modern web development, React, JavaScript, backend development, and AI. #ReactJS #React #JavaScript #WebDevelopment #FrontendDevelopment #ReactReconciliation #ReactFiber #VirtualDOM
