What is the Vue.js reactivity system?

The Vue.js reactivity system is a core feature that allows Vue to efficiently update the DOM when data changes.

How does it track changes in data?

Vue uses getters and setters to observe changes in data properties, allowing it to reactively update the UI.

Can you explain how it differs from React's state management?

Unlike React's virtual DOM diffing, Vue's reactivity system directly tracks dependencies, making updates more efficient.

What are some common pitfalls when using Vue's reactivity?

Common pitfalls include not using Vue.set for adding new properties and mutating arrays directly without using Vue methods.
