	}

	function remove() {

</script>

<input placeholder="filter prefix" bind:value={prefix}>

<select bind:value={i} size={5}>
	{#each filteredPeople as person, i}
		<option value={i}>{person.last}, {person.first}</option>
	{/each}
</select>

<label><input bind:value={first} placeholder="first"></label>
<label><input bind:value={last} placeholder="last"></label>

<div class='buttons'>
	<button on:click={create} disabled="{!first || !last}">create</button>
	<button on:click={update} disabled="{!first || !last || !selected}">update</button>
	<button on:click={remove} disabled="{!selected}">delete</button>
</div>

<style>
	* {
		font-family: inherit;
		font-size: inherit;
	}

	input {
		display: block;
		margin: 0 0 0.5em 0;
	}

	select {
		float: left;
		margin: 0 1em 1em 0;
		width: 14em;
