Loro muine nampilake elemen sacara kondisional, nanging caranya beda — v-if nambah/nyilang elemen saka DOM; v-show tetep ana ing DOM lan ngalih-alih CSS display sapadane.
<template>
<p v-if="isVisible">Rendered only when true (removed from DOM when false)</p>
<p v-show="isVisible">Always in the DOM; just display:none when false</p>
</template>
<!-- v-if="false" → the element doesn't exist at all -->
<!-- (nothing in the DOM) -->
<!-- v-show="false" → the element exists but is hidden -->
<p style="display: none">...</p>
v-if nduweni biaya pengalihan sing luwih dhuwur (ndandani/ngrusak elemen lan komponene, njalanake lifecycle hooks saben wektu) nanging nol biaya yen kondisyone false (ora ana sing dirender).v-show nduweni biaya awal sing luwih dhuwur (tansah dirender, sanajan didhelikake) nanging pengalihan murah (mung owah CSS).Toggles often (tabs, dropdowns) → v-show (cheap to flip)
Rarely changes / may never render → v-if (skip rendering entirely)
Expensive content rarely shown → v-if (don't pay to build it)
<template>
<p v-if="status === 'loading'">Loading...</p>
<p v-else-if="status === 'error'">Error!</p>
<p v-else>Done</p>
</template>
v-if sumukunga v-else-if/v-else chain; v-show ora (mung ngalih-alih siji elemen).
v-show ora gumana ing wrapper <template> (ora ana elemen kanggo ngatur display); v-if bisa.
Millih sing tepat iku kaputusan performa sing nyata: v-show kanggo barang-barang sing asring dialih-alih (DOM tetep, pengalihan murah), v-if kanggo barang-barang sing kondisional/arang utawa larang (aja dirender nganti diperlu).
Millih salah — contone, v-show ing konten sing abot sing biasane didhelikake — nyisir karya rendering.
