What Is Vue.js?

Vue.js is a progressive JavaScript framework used for building user interfaces (UIs) and single-page applications (SPAs). Created by Evan You and maintained by a community of open-source developers, Vue combines the best features of React and Angular while keeping things lightweight, flexible, and easy to learn.

Designed to be incrementally adoptable, Vue allows developers to use it as a simple script in an HTML page or scale it up for building complex applications with routing, state management, and component architecture.

Key Features of Vue.js

1. Reactive Data Binding
   Automatically updates the DOM when the application state changes, using Vue’s reactivity system.
2. Component-Based Architecture
   Break down UIs into reusable, self-contained components for better scalability and maintainability.
3. Single File Components (.vue files)
   Write HTML, JavaScript, and CSS in a single file, improving readability and organization.
4. Directives & Template Syntax
   Built-in directives like v-if, v-for, and v-bind allow dynamic rendering in HTML templates.
5. Vue CLI
   Official command-line interface for scaffolding, developing, and building Vue applications.
6. Vue Router
   Adds navigation and routing features to support single-page applications.
7. Pinia (or Vuex)
   Official state management library used to share data between components.
8. Transitions & Animations
   Easily add smooth transitions between views and elements.
