What are common Vue performance anti-patterns?
Article Introduction:Common Vue performance anti-patterns include: 1. unnecessary responsive data, 2. Frequent execution of functions in templates, 3. Abuse of v-if and v-show, 4.

Ignore the correct use of key attributes; the corresponding optimization suggestions are: only set the really needed data as responsive and use Object.freeze(), replace template functions with computed attributes, use v-show to switch high-frequency v-if, use state management library to reduce coupling, and always use unique identifiers as key.

How to manage subscriptions in Vue components?
Article Introduction:The key to managing subscriptions in Vue components is to avoid memory leaks and duplicate triggers. Three key points need to be followed: 1. Use beforeUnmount or onBeforeUnmount to clean up the subscription; 2. Avoid creating new subscriptions directly in the template; 3. Encapsulate subscription logic with composable functions for reuse and unified management. By unsubscribing before component uninstallation, moving subscription logic out of templates and saving to responsive data, and encapsulating common logic, performance and maintenance can be effectively improved, ensuring "who creates and cleanses", thus preventing memory leaks and unexpected behaviors.
