v-memo is a directive for performance optimization in Vue3, which avoids unnecessary updates by memorizing rendering results. It receives an array of dependencies, and will re-render the corresponding elements and subcomponents only when the values in the array change. It is often used to reduce repeated rendering when rendering long lists. Note when using: it must be used in conjunction with v-for, and the dependencies should be selected as basic types as possible, and the key attribute should be set correctly. Compared with v-once, v-memo supports dynamic updates, which is suitable for scenarios where data may change but remain stable most of the time. It is recommended to use it when the component structure is complex, the rendering overhead is large, and the updates are frequent but not all changes to improve performance.
