# Vue.js

> Vue.js is a progressive JavaScript framework for building user interfaces and single-page applications, based on reactive rendering of components.

**Vue.js** is an open-source [JavaScript](https://nodea.io/en/glossary/javascript) framework for building user interfaces and single-page applications (SPAs). It is called progressive because it can be adopted gradually — from a simple script that enlivens part of an existing page all the way to a full application architecture with routing, state management and build tooling.

## Reactivity and components

The foundation of Vue is a reactive data model: when the application state changes, the framework automatically and efficiently updates only the parts of the view affected by the change, using a [virtual DOM](https://nodea.io/en/glossary/virtual-dom). Interfaces are built from components — self-contained, reusable building blocks that combine template, logic and styling, which makes code easier to maintain and extend.

## Vue compared to other frameworks

Vue is often compared with [React](https://nodea.io/en/glossary/react) and [Angular](https://nodea.io/en/glossary/angular). It differs from React in its template syntax, which stays close to plain HTML, and in a gentler learning curve, and from Angular in its smaller size and greater flexibility. Like every modern front-end [framework](https://nodea.io/en/glossary/framework), Vue works with tools that bundle code, supports server-side rendering for better SEO and performance, and has a rich ecosystem of libraries. Its large community, extensive documentation and many ready-made libraries shorten the time needed to build common interface features and make it easier to find developers who know it. For a product owner, the choice of framework affects development speed, the availability of engineers and long-term maintenance cost, so the decision is best made in the context of a specific project rather than fashion.

### Is Vue.js suitable for large applications?

Yes. Vue scales from simple widgets attached to an existing page all the way to large single-page applications with routing and state management, which is why it is called a progressive framework.
