What is Vue.js reactivity and how does it work?

Vue.js reactivity is a system that allows the UI to automatically update when the underlying data changes. It uses a reactive data model.

Can you explain how Vue.js tracks changes in data?

Vue.js uses getters and setters to observe changes in data properties. When a property is accessed, it tracks the dependency, and when it changes, it triggers updates.

What are the benefits of using reactivity in Vue.js?

Reactivity simplifies state management, reduces boilerplate code, and enhances performance by only updating the parts of the DOM that need to change.

Are there any limitations to Vue.js reactivity?

Yes, Vue.js reactivity has limitations, such as not detecting property additions or deletions unless they are made using Vue's methods.

How does Vue.js reactivity compare to React's state management?

Vue.js reactivity is more automatic and less verbose than React's state management, which often requires explicit updates using hooks.
