Svelte svelte-show-action is the equivalent of v-show in vuejs, or ng-show in angularjs. svelte-show-action will hide the element without adding any div block or destroying the component.
<script>
import show from "svelte-show-action";
let display = true;
$: text = display ? 'Hide' : 'Show';
</script>
<button on:click={() => (display = !display)}>
{text}
</button>
<div use:show={display}>
