How does reactivity work in Vue 3 forms?

Can you explain how reactivity works in Vue 3 forms?

Sure! In Vue 3, reactivity is achieved using the Composition API, which allows you to create reactive state using the ref and reactive functions.

What are ref and reactive? How do I use them in forms?

ref is used for primitive values, while reactive is for objects. In forms, you can use ref for input values and reactive for form data objects.

Can you show me a simple example of a reactive form?

Absolutely! Here's a basic example:

import { ref } from 'vue';

export default {
  setup() {
    const name = ref('');
    return { name };
  }
};

This creates a reactive name variable that updates as the user types.

What about form validation in Vue 3?

For form validation, you can use libraries like VeeValidate or create custom validation logic using computed properties.
