Understanding the Virtual DOM and React Reconciliation
Understanding the Virtual DOM and React Reconciliation React’s efficiency in rendering UI updates is largely thanks to its Virtual DOM and a process called Reconciliation . Whether you're a frontend developer aiming to deepen your understanding or a future solution architect looking to master optimization techniques, this post is for you. What is the Virtual DOM? The Virtual DOM (VDOM) is a lightweight, in-memory representation of the actual DOM. React creates this virtual structure to manage and update UI changes more efficiently. How it works: When you update the UI, React creates a new Virtual DOM. It compares this new VDOM with the previous one (called diffing ). Only the parts that changed are updated in the real DOM. Why it's efficient: Direct DOM manipulation is costly in terms of performance. The Virtual DOM allows React to minimize actual changes, leading to faster rendering and smoother UI.
