v-show directive in Vue

Another option for conditional display is the v-show directive. It is used very similarly:

<template>
	<p v-show="isAuth">
		+++
	</p>
</template>

The difference is that an element with v-show will always be rendered and remain in the DOM, and only its CSS property display will be toggled.

The v-if directive performs "true" conditional rendering, as it ensures that event listeners and child components within the block are properly destroyed and recreated when the condition is toggled.

The v-if directive is also lazy: if the condition is false at the time of the initial rendering, it will do nothing - the conditional block will not be rendered until the condition becomes true.

In comparison, v-show is much simpler - the element is always rendered, regardless of the initial state, with CSS-based toggling.

In general, v-if has higher switching costs, while v-show has higher initial draw costs. So use v-show if switching will be frequent, and prefer v-if if the condition may not change during execution.

The v-show directive cannot be used on a template element and does not work with v-else.

Given a paragraph and a button, make the paragraph toggle when the button is pressed.

Explain the differences between the v-show and v-if directives.

Tell me when it is better to use the v-show directive, and when - v-if.

Please tell me what limitations the v-show directive has.
