📘 Vue Introduction – Getting Started with the Progressive JavaScript Framework

🔍 What is Vue.js?

Vue in a Nutshell

Vue.js is a modern JavaScript framework used to build web user interfaces. It’s lightweight, fast, and flexible. Whether you’re crafting a small widget or a full-blown web app, Vue’s got your back.

Why Developers Love Vue

Vue is developer-friendly. Its syntax is clean, setup is minimal, and you can start building something useful in minutes.

📜 History and Evolution of Vue

The Creator – Evan You

Vue was created by Evan You, a former Google engineer. He wanted a lightweight framework that combined the best of Angular and React—without the bloat.

How Vue Evolved Over the Years

Since its release in 2014, Vue has grown rapidly. From Vue 1 to the current Vue 3, it’s become more powerful, modular, and future-ready.

⚙️ Core Features of Vue.js

Declarative Rendering

You define the UI based on the data, and Vue takes care of keeping it in sync. It’s magical.

Reactive Data Binding

Update the data, and Vue updates the DOM instantly. It’s like your HTML listens to your JavaScript.

Component-Based Architecture

Split your app into smaller pieces (components) and manage them easily.

🤔 Why Choose Vue Over Other Frameworks

Vue vs. React

Vue offers a more opinionated setup and easier learning curve. No JSX here—just HTML templates.

Vue vs. Angular

Angular is heavyweight and complex. Vue is lightweight and modular. You choose your tools.

Learning Curve & Documentation

Vue has some of the best docs in the industry. Even a beginner can start making apps in a day.

🛠️ Setting Up Vue

Using CDN (Fastest Way)

<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>

Drop this into your HTML, and you’re good to go!

Vue CLI (Professional Projects)

npm install -g @vue/cli
vue create my-app
cd my-app
npm run serve

Perfect for larger, scalable applications.

Vue + Vite (Modern Build Tools)

For lightning-fast development with hot module reload and ESM:

npm create vite@latest my-vue-app --template vue

🔤 Basic Vue Syntax & Concepts

The Vue Instance

const app = Vue.createApp({
  data() {
    return { message: 'Hello Vue!' }
  }
}).mount('#app')

Template Syntax

<p>{{ message }}</p>

Interpolation is clean and readable.

Directives – `v-if`, `v-for`, `v-bind`, and `v-on`

<p v-if="seen">Now you see me</p>
<li v-for="item in list" :key="item.id">{{ item.text }}</li>

Powerful and simple!

🚀 Creating Your First Vue App

HTML + Vue via CDN

<div id="app">
  <input v-model="name" />
  <p>Hello, {{ name }}</p>
</div>

Writing Reactive Code

Vue.createApp({
  data() {
    return { name: '' }
  }
}).mount('#app')

Binding Events and Data

<button v-on:click="greet">Greet</button>

🧩 Exploring Components in Vue

What are Components?

They’re reusable chunks of UI. Think: buttons, cards, or navbars.

Creating a Custom Component

app.component('my-header', {
  template: `<h1>This is a Header</h1>`
})

Props and Events in Action

Pass data with props, communicate with $emit. Like sending messages between roommates.

Add pages with ease:

import { createRouter, createWebHistory } from 'vue-router'
