How can I use reactive properties in Vue?

How can I use reactive properties in Vue?

In Vue, you can create reactive properties using the data option in your component. For example, you can define a data property like this: data() { return { count: 0 }; }.

Can you show me an example of how to update a reactive property?

Sure! You can update a reactive property by simply assigning a new value to it. For instance, this.count += 1; will increment the count.

What happens if I try to modify a property that isn't reactive?

If you modify a non-reactive property, Vue won't be able to track changes, and the UI won't update automatically.

Are there any best practices for using reactive properties?

Yes, it's best to keep your data properties simple and avoid deep nesting. Use computed properties for derived state.
