How to pass props as initial data in Vue.js?

To pass props as initial data in Vue.js, we can set the prop value as an initial value of a reactive property.

For instance, we write

<script>
export default {
  //...
  props: {
    record: {
      type: Object,
      required: true,
    },
  },

  data() {
    return {
      recordLocal: { ...this.record },
    };
  },
  //...
};
</script>

to set the recordLocal reactive property to a copy of the record prop as its initial value.

We register the record prop in the props property.
