What are some effective data handling techniques in Vue.js?

In Vue.js, effective data handling techniques include using Vuex for state management, computed properties for derived state, and watchers for reacting to data changes.

Can you explain how Vuex works for state management?

Vuex is a state management library for Vue.js applications. It centralizes the state in a single store, allowing components to access and modify the state in a predictable way.

What are computed properties and how do they differ from methods?

Computed properties are cached based on their dependencies and only re-evaluate when those dependencies change, while methods are re-evaluated every time they are called.

How can I use watchers to respond to data changes?

Watchers allow you to perform asynchronous or expensive operations in response to changing data. You define a watcher on a specific data property, and it triggers a function whenever that property changes.
