WebThe Diffing Algorithm When diffing two trees, React first compares the two root elements. The behavior is different depending on the types of the root elements. Elements Of Different Types Whenever the root elements have different types, React will tear down the old tree and build the new tree from scratch. 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.

"WebJan 25, 2016 · React implements a heuristic O (n) algorithm based on two assumptions: 1) Two elements of different types will produce different trees. 2) The developer can hint at which child elements may be stable across different renders with a key prop. In practice, these assumptions are valid for almost all practical use cases. " - React diffing algorithm

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. WebJul 26, 2024 · Breadth-First Search. React traverses the DOM tree using the breadth-first search algorithm. In this algorithm, nodes are traversed from top to bottom and left to right. If React finds any element that is modified, it will, by default, re-render that subtree without proceeding pain further to check the depth of the tree.

WebOct 18, 2016 · The algorithm React uses to diff one tree with another to determine which parts need to be changed. update A change in the data used to render a React app. Usually the result of `setState`. Eventually results in a re-render. The central idea of React's API is to think of updates as if they cause the entire app to re-render.

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.
