Vue Intro

This lesson is part of Vue · All levels

Summary

This lesson explains what Vue is and the declarative philosophy behind it. Instead of instructing the browser step by step through manual DOM manipulation, you describe how the display should look, and then Vue keeps the display always in sync with the data. The key concept is reactivity: when a data changes, the part of the display that depends on it is automatically updated.

Key points

Vue uses a declarative approach: describing the end result of the view, not the manipulation of the DOM.
Reactivity makes the UI automatically update as the data changes.
The Vue application is state-centered (reactive data) as the single source of truth.
Vue can be used over a CDN without a build process.
