What are the limitations of Vue's reactivity system?

Vue's reactivity system has some limitations, such as not detecting property additions or deletions on objects, and it can struggle with deeply nested data structures.

Can you explain why Vue doesn't detect property additions?

Vue uses getters and setters to track changes, but it can't intercept property additions or deletions because they aren't defined in the initial data object.

What can I do to work around these limitations?

You can use Vue's Vue.set() method to add new properties to an object, which ensures reactivity. For deeply nested structures, consider using libraries like Vuex for state management.

Are there any performance implications of these limitations?

Yes, if you have a lot of reactive properties or deeply nested data, it can lead to performance issues. It's important to optimize your data structures.
