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. 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.
