Vue.js 是一套构建用户界面的 渐进式框架。与其他重量级框架不同的是，Vue 采用自底向上增量开发的设计。Vue 的核心库只关注视图层，并且非常容易学习，非常容易与其它库或已有项目整合。另一方面，Vue 完全有能力驱动采用单文件组件和 Vue 生态系统支持的库开发的复杂单页应用。

Vue.js 的目标是通过尽可能简单的 API 实现响应的数据绑定和组合的视图组件。

如果你是有经验的前端开发者，想知道 Vue.js 与其它库/框架的区别，查看对比其它框架。(Vue.js is a progressive framework for building user interfaces. Unlike other heavyweight frameworks, Vue uses a bottom-up incremental design. The core library of Vue focuses only on the visual layer, and it is very easy to learn, and it is easy to integrate with other libraries or existing projects. On the other hand, Vue is fully capable of driving complex single page applications that are developed using single file components and Vue ecosystem supported libraries.
The goal of Vue.js is to implement response data binding and composite view components by as simple as API.
If you're an experienced front-end developer, and you want to know the difference between Vue.js and other libraries / frameworks, look at other frameworks.)
