Whenever it encounters root elements that have changed, it tears down the nodes whose states have changed and remounts them.

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. WebReact’s diffing algorithm (called Reconciliation) uses component identity to determine whether it should update the existing subtree or throw it away and mount a new one. If the component returned from render is identical (===) to the component from the previous render, React recursively updates the subtree by diffing it with the new one.
