Computationally intensive computed variable within v-if: does it always run?

[MarcelloTheArcane]

My question is about vue 2.6.14.

Assume I have the following layout:

<div v-if="show">
  {{ computationallyIntensiveComputedVariable }}
</div>
<button @click="show = true">Show</button>

show defaults to false. If I never click the "Show" button, does the computationallyIntensiveComputedVariable ever run?

Computed properties are evaluated only when their value is being read, so the answer would be: No. Provided that this is the only place you access it.
