Alright guyss welcome back….

Function Callback()

Button.svelte

<script>
    export let count;
    
	export let handleClick = () => {
        count += 1;
    };
</script>

<style>

</style>

<button on:click={handleClick}>
    count: {count}
</button>

App.svelte

<script>
	import Button from "./Button.svelte"
	export let name;

	let count = 0;
    
	const increment = () => {
		count += 2;
	};
</script>

<main>
	<h1>Hi {name}! {count}</h1>
	<p>Visit the <a href="https://svelte.dev/tutorial">Svelte tutorial</a> to learn how to build Svelte apps.</p>
	<Button {count} handleClick={increment} />
	<Button count={0} />
</main>

jadi disini kita telah mencoba mengoverride function ya dengan dengan cara mempassingnya… jadi value default nya ada +1 namun di override menjadi +2

result

oke cukup menarik juga ya… link github ada disini… cyaaa…
