What is the Vue 3 reactivity system?
An example of an AI chatbot conversation about Vue 3's reactivity system and its features.
What is the Vue 3 reactivity system?
The Vue 3 reactivity system is a core feature that allows Vue to efficiently track changes in data and update the DOM automatically.
How does it differ from Vue 2?
Vue 3 uses a Proxy-based implementation for reactivity, which is more efficient and allows for better performance compared to Vue 2's Object.defineProperty.
Can you explain how to use it in a component?
Sure! In Vue 3, you can use the ref and reactive functions to create reactive data. For example, const count = ref(0); makes count reactive.
What are some common pitfalls when using the reactivity system?
Common pitfalls include not using ref or reactive correctly, and trying to mutate reactive objects directly without using the provided methods.
