Conclusion
You can pass event handlers to components like any other prop. In Stepper.svelte, add increment and decrement props...
Stepper
<script>
let { increment, decrement } = $props();
</script>...and wire them up:
Stepper
<button onclick={decrement}>-1</button>
<button onclick={increment}>+1</button>In App.svelte, define the handlers:
<Stepper
increment={() => value += 1}
decrement={() => value -= 1}
/>previous next
