🔍 Vue Overview – Everything You Need to Know About Vue.js
👋 Introduction to Vue
What is Vue.js?
Vue.js is a progressive JavaScript framework used to build interactive user interfaces and single-page applications. It’s simple to start with but powerful enough to handle large-scale apps.
Who Created Vue and Why?
Vue was created by Evan You, a former Google engineer. He wanted to build something lightweight like jQuery but structured like Angular—thus Vue was born in 2014.
🧠 Vue’s Core Philosophy
Progressive Framework Explained
Vue is called “progressive” because you can use as little or as much of it as you need. Start with a CDN and sprinkle in features or go full SPA with Vue CLI.
Declarative and Reactive Foundations
Vue lets you declare how your UI should look, and it takes care of updating it reactively when your data changes.
⚙️ Key Features of Vue
Virtual DOM
Vue uses a virtual DOM to boost performance and minimize direct manipulation of the real DOM.
Data Binding & Directives
Use v-model, v-if, v-for, and more to bind data and control DOM behavior.
Component-Based Architecture
Everything in Vue is a component—buttons, modals, even entire pages.
Transition Effects & Animations
Vue makes it easy to add transitions and animations using built-in <transition> wrappers.
🔄 Vue 2 vs Vue 3
What Changed in Vue 3?
Vue 3 brought:
- Better performance
- Smaller bundle size
- Composition API
- Full TypeScript support
Composition API vs Options API
The Composition API gives you more control and code reuse, while Options API is simpler and more familiar for beginners.
🌐 Vue Ecosystem
