WebAny existing DOM elements inside are replaced when render is called. Later calls use React’s DOM diffing algorithm for efficient updates. createRoot() does not modify the container node (only modifies the children of the container). It may be possible to insert a component to an existing DOM node without overwriting the existing children. 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.

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. WebOct 23, 2024 · Considering that the app's state changes, React uses its diffing algorithm (very similar to how Git compares changes in files) to compare the root elements in the virtual DOM and real DOM. Whenever it encounters root elements that have changed, it tears down the nodes whose states have changed and remounts them.
