What are some examples of reactivity systems in programming?

Reactivity systems allow applications to automatically update in response to data changes. Examples include React, Vue.js, and Svelte.

How does React handle reactivity?

React uses a virtual DOM to efficiently update the UI. When state changes, it re-renders only the affected components.

Can you explain how Vue.js differs from React in terms of reactivity?

Vue.js uses a reactive data model with a dependency tracking system, allowing it to automatically update the DOM when data changes.

What are the benefits of using a reactivity system?

Benefits include improved performance, easier state management, and a more intuitive way to build interactive user interfaces.

Are there any downsides to using reactivity systems?

Yes, potential downsides include increased complexity in understanding reactivity and possible performance issues with large applications.
