Just as in React, Svelte also exposes various lifecycle methods that you can use to execute code when a component mounts, destroys, or updates:

Copied to clipboard!
<script>
    import { onMount, beforeUpdate, afterUpdate, onDestroy } from 'svelte';

    onMount(() => {
        console.log('The component has been mounted');
    });

    beforeUpdate(() => {
        console.log('The component is about to update');
    });

    afterUpdate(() => {
        console.log('The component has been updated');
    });

    onDestroy(() => {
        console.log('The component has been destroyed');
    });
</script>
