What is the Vue reactivity system?

Can you explain how the Vue reactivity system works?

Sure! The Vue reactivity system allows Vue to track changes in data and automatically update the DOM when data changes.

How does Vue know when to re-render the components?

Vue uses a dependency tracking system. When a component is rendered, it records which data properties it depends on, and when those properties change, Vue knows to re-render the component.

What are getters and setters in this context?

Getters and setters are functions that allow you to define how properties are accessed and modified. In Vue, they help in tracking changes to reactive properties.

Can you give an example of a reactive property?

Certainly! If you have a data property like 'count', and you change it using 'this.count++', Vue will automatically update any part of the UI that depends on 'count'.
