Svelte – Keyed Each Blocks

---

Alright guys welcome back to our channel… balik lagi bersama Svelte di project kita.. kali ini kita masuk ke Each statement disertai dengan keys nya… okay lansung aja kita buat file dulu..

components/things/KeyEachThingComp.svelte

<script>
	// `current` is updated whenever the prop value changes...
	export let current;

	// ...but `initial` is fixed upon initialisation
	const initial = current;
</script>

<p>
	<span style="background-color: {initial}">initial</span>
	<span style="background-color: {current}">current</span>
</p>

<style>
	span {
		display: inline-block;
		padding: 0.2em 0.5em;
		margin: 0 0.2em 0.2em 0;
		width: 4em;
		text-align: center;
		border-radius: 0.2em;
		color: white;
	}
</style>

dan kemudian kita buat lagi file components/KeyEachThing.svelte

<script>
	// `current` is updated whenever the prop value changes...
	export let current;

	// ...but `initial` is fixed upon initialisation
	const initial = current;
</script>

<p>
	<span style="background-color: {initial}">initial</span>
	<span style="background-color: {current}">current</span>
</p>

<style>
	span {
		display: inline-block;
		padding: 0.2em 0.5em;
		margin: 0 0.2em 0.2em 0;
		width: 4em;
		text-align: center;
		border-radius: 0.2em;
		color: white;
	}
</style>

jadi yang kita import ke App.svelte kita adalah yang tanpa Comp jadi akan seperti ini :

<script>
	
	import Counter from './components/Counter.svelte'
	import Toggle from './components/Toggle.svelte'
	import Img from './components/Img.svelte'
	import String from './components/String.svelte'
	import Statement from './components/Statement.svelte'
	import Condition from './components/Condition.svelte';
	import Nested from './components/Nested.svelte';
	import Info from './components/Info.svelte';
	import IfLogin from './components/IfLogin.svelte'
	import Comparison from './components/Comparison.svelte'
	import EachYoutube from './components/EachYoutube.svelte'
	import KeyEachThing from './components/KeyEachThing.svelte'

	export let name;

	const pkg = {
		name: 'svelte',
		version: 3,
		speed: 'blazing',
		website: 'https://svelte.dev'
	};
</script>
