Write Vue like you write React - part 2

index.js

import { defineComponent, ref, watchEffect } from 'vue';

export const Counter = defineComponent({
  props: ['limit', 'onLimit'],
  setup(props) {
    const count = ref(0);
    const handler = () => count.value++;

    watchEffect(
      () => (count.value >= props.limit) ? props.onLimit() : null
    );

    return () => <button type="button" onClick={handler}>
      Count: {count.value}
    </button>;
  }
});
