Vue.Js Vue (pronounced /vjuː/, like  view ) is a  progressive framework  for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with  modern tooling  and  supporting libraries . If you’d like to learn more about Vue before diving in, we  created a video  walking through the core principles and a sample project. If you are an experienced frontend developer and want to know how Vue compares to other libraries/frameworks, check out the  Comparison with Other Frameworks .

How do they manage all that a blazing speed. To do that they come up a library called react.js Imagine a post on facebook. Now this post which is a  container  consists of multiple small parts like likes,comments,share,commentbox called  components.  So yes with react you page can ...
