Save Component Characteristics in a type-safe array

Is it possible in Svelte to define a strongly typed array that matches the properties exported by a specific component?

For instance, if I have the following code snippet, const things = [], is there a way for Svelte to recognize that each item within the array should have a name and an age property based on the component's exports?

<script lang="ts">
  // Thing.svelte

  export let name: string;
  export let age: number;
</script>
<script lang="ts">
  // +Page.svelte

  import Thing from '$lib/Thing.svelte';

  const things = [{
    naem: "Bob",
    age: 36  
  }];
</script>

{#each things as thing}
  <Thing {...thing} />
{/each}

I would appreciate any guidance on how I can achieve this without creating my own custom ThingOptions type. Thank you!

Svelte provides convenient utility types for achieving this:

import type { ComponentProperties } from 'svelte';
const elements: ComponentProperties<Element>[] = [ ... ];
