What are some common pitfalls in Vue's reactivity system?
Some common pitfalls include not using Vue.set for adding reactive properties, and misunderstanding how reactivity works with arrays.
Can you explain why using Vue.set is important?
Using Vue.set is crucial because it ensures that new properties are made reactive, allowing Vue to track changes.
What happens if I don't use Vue.set?
If you don't use Vue.set, the new property won't be reactive, and Vue won't update the DOM when it changes.
Are there any other common mistakes I should be aware of?
Yes, another mistake is directly mutating props, which can lead to unexpected behavior in your components.
