Vue is a set of progressive framework for building user interface. Different from other large-scale frameworks, Vue is designed to be able to apply layer by layer from bottom to top. Vue's core library only focuses on visual layers, which is not only easy to use, but also easy to integrate with third-party libraries or existing projects. On the other hand, when used in combination with modern tool chains and various support class libraries, Vue can also provide drivers for complex single page applications.The goal of vue.js is to implement the data binding and combined view components of the response through the simplest possible API.
