Vue.js 面试题与答案
问题 6. Explain Vue components and their advantages.
Vue components are reusable and self-contained units that encapsulate a specific piece of functionality. They promote code reusability, maintainability, and separation of concerns in a Vue application.
问题 7. What is Vuex, and why would you use it?
Vuex is the state management library for Vue.js applications. It helps manage the state of the application in a centralized store, making it easy to maintain and share state across components.
问题 8. Explain the concept of two-way data binding in Vue.js.
Two-way data binding in Vue.js allows automatic synchronization of data between the model and the view. It is achieved using the v-model directive, which binds an input element to a variable and updates both the input value and the variable when either changes.
问题 9. What is a computed property in Vue.js?
A computed property in Vue.js is a property whose value is derived from other reactive data. It is recalculated only when its dependencies change, providing a way to perform calculations on the fly without re-rendering unnecessarily.
问题 10. Explain the concept of mixins in Vue.js.
Mixins in Vue.js are a way to reuse and share logic across multiple components. They allow you to encapsulate and distribute reusable functionality by merging the properties and methods of a mixin into a component.
