💚 Vue.js CourseLesson 1 of 10 · 10% complete
Vue.js is a progressive JavaScript framework for building UIs. Unlike React (a library) or Angular (full framework), Vue is the sweet spot — easy to learn, powerful at scale.
Why Vue?
// Vue's design philosophy:
// 1. Progressive — use as much or as little as you want
// (Add to one HTML file, or build full SPA)
// 2. Approachable — if you know HTML, CSS, JS, you can start
// 3. Performant — fast reactive system, small bundle size
// 4. Versatile — works for simple widgets to complex appsVue vs React
// React:
// - Library (you choose routing, state, etc.)
// - JSX (JS-first, HTML inside JS)
// - More flexible but more decisions
// Vue:
// - Framework (comes with official Router, Pinia state)
// - SFC (Single File Components — HTML + CSS + JS in one .vue file)
// - More opinionated, easier to start
// - v-if, v-for, v-model directives (HTML-first feel)Vue Powers
