WebJul 11, 2024 · React uses virtual DOM to enhance performance. Virtual dom is a lightweight copy of the real DOM stored in memory. When there is a change of state or prop, React creates a virtual DOM. It uses the diffing algorithm to compare the previous virtual DOM with the updated virtual DOM.

WebJan 25, 2024 · React uses a specific diffing algorithm, called the "Reconciliation algorithm" to determine the changes made to a component's virtual DOM. This algorithm compares the virtual DOM tree of the previous render with the virtual DOM tree of the current render. It then identifies the differences between the two trees and updates the actual DOM ... WebSep 13, 2024 · From our research, the vast majority of the time spent by applications built with React-like libraries lies in the application code. We wish optimizing the diffing algorithm was more fruitful for anything other than winning benchmark, but that does not match our experience. The library code was a small fraction of the executed code in real apps ...

WebMar 15, 2024 · React is a JavaScript library for building user interfaces. At its core lies the mechanism that tracks changes in a component state and projects the updated state to the screen. In React we know this process as reconciliation. We call the setState method and the framework checks if the state or props have changed and re-renders a component on UI.
