This post is about what the v-once command in Vue does. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.
v-once
v-once associated instances are rendered only once. After rerendering, the instance and all its children are treated as static content skips, which can be used to optimize update performance.
