Nettet18. okt. 2024 · React does this by maintaining the state of the Element tree from the previous render and comparing it to the new Element tree using an diffing algorithm. The problem of comparing the previous tree (or graph) with the new tree is known in Computer Science as the Graph Edit Distance Problem . Nettet15. mar. 2024 · React’s docs provide a good high-level overview of the mechanism: the role of React elements, lifecycle methods and the render method, and the diffing algorithm applied to a component’s children. The tree of immutable React elements returned from the render method is commonly known as the “virtual DOM”.

NettetThe 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. Nettet17. mai 2024 · Reconciliation is the process through which React updates the DOM. When a component’s state changes, React has to calculate if it is necessary to update the DOM. It does this by creating a virtual DOM and comparing it with the current DOM. In this context, the virtual DOM will contain the new state of the component. services day alton towers 2023
