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>

The 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.
