Vue Tip: Memoize a Sub-Tree of the Template Using v-memo
The v-memo directive is like a computed prop for the template and be used on both elements and components:
<template> <div v-memo="[valueA, valueB]"> <!-- ... --> </div></template>
v-memo directive expects a fixed-length array of dependency values to compare for the memoization.
If every value in the array was the same as last render, then updates for the entire sub-tree will be skipped.
