Common mistakes to avoid Vue.js virtual DOM include: 1. Avoid unnecessary re-rendering, using watch or v-once optimization; 2. Use unique identifiers as keys, rather than indexes; 3. Avoid excessive use of watchers, prioritizing computed properties or methods; 4. Use lifecycle hooks correctly to ensure that the operation is carried out at the appropriate time.

Vue.js uses virtual DOM to bring significant performance improvements and development experience optimization. 1) Virtual DOM reduces the number of real DOM operations and avoids redrawing and rearrangement. 2) Efficient algorithms compare new and old virtual DOM trees and only update the necessary parts. 3) The responsive system combines virtual DOM to accurately update the components that depend on data. 4) It is necessary to note that virtual DOM may introduce additional overhead, and applicable scenarios need to be carefully evaluated.

Vue.js efficiently handles updates through virtual DOM. The specific steps are as follows: 1) Generate a new virtual DOM tree when the component state changes; 2) compare with the old tree through the diffing algorithm to find the changed part; 3) Only update the changed DOM part. In practical applications, use v-if/v-show and key attributes to optimize performance, reduce unnecessary DOM operations, and improve user experience.

The key to optimizing Vue application performance is to start from four aspects: initial loading, responsive control, rendering efficiency and dependency management. 1. Use routes and components to lazy load, reduce the initial package volume through dynamic import; 2. Avoid unnecessary responsive data, and store static content with Object.freeze() or non-responsive variables; 3. Use v-once instructions, compute attribute cache and keep-alive components to reduce the overhead of repeated rendering; 4. Monitor the package volume, streamline third-party dependencies and split code blocks to improve loading speed. Together, these methods ensure smooth and scalable applications.
