What are the limitations of reactivity in Vue.js?
An example of an AI chatbot conversation about Vue.js reactivity limitations.
What are the limitations of reactivity in Vue.js?
Vue.js reactivity has some limitations, such as not detecting property additions or deletions on objects, and issues with arrays.
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 reactive by default.
What can I do to make properties reactive?
You can use Vue's Vue.set() method to add new properties to an object and make them reactive.
Are there any performance concerns with Vue's reactivity system?
Yes, excessive reactivity can lead to performance issues, especially with large data sets or deeply nested objects.
How does Vue 3 improve upon these limitations?
Vue 3 introduces the Composition API and Proxy-based reactivity, which improves performance and allows for better handling of reactivity.
