How does data binding work in Vue's Options API?

In Vue's Options API, data binding allows you to connect your data properties to the DOM. You define data in the data function, and Vue automatically updates the DOM when the data changes.

Can you give me an example of how to set up data binding?

Sure! You can set up data binding by defining a data function in your Vue component. For example:

export default {
  data() {
    return {
      message: 'Hello, Vue!'
    };
  }
};

Then, in your template, you can use {{ message }} to display the data.

What happens if I change the data property?

If you change the data property, Vue will automatically re-render the DOM to reflect the new value. For instance, if you set this.message = 'New message!', the displayed message will update instantly.

Are there any limitations to data binding in the Options API?

Yes, while the Options API is powerful, it can become cumbersome for larger applications. You might find it harder to manage state compared to the Composition API, which offers more flexibility.
