Vue.js

Vue templates bind your data to HTML — the foundation of everything in the framework.

Vue's magic is that when data changes, the UI updates itself — you must understand how.

User interaction starts with events — clicks, typing, and form submissions.

Instead of computing the same thing twice, computed properties do it for you efficiently.

Components let you split the UI into small, reusable pieces — the heart of Vue.

.vue files and <script setup> are the modern, preferred way to write Vue.

You need to know when a component mounts or unmounts to fetch data or clean up.

To build truly flexible components, you need advanced ways to pass content and data.

Any real single-page app needs navigation between pages — that's Vue Router's job.

When state grows and is shared across many components, Pinia centralizes it cleanly.

TypeScript with Vue gives you safety and autocomplete for props, state, and emits.

Nuxt gives Vue superpowers: server rendering, automatic routing, and better SEO.

Tests give you confidence your code works and catch bugs before users do.

A large Vue app can easily get slow — learn to write fast, maintainable code.
