Add interactive GUI and website for learning and testing JavaScript concepts

[Copilot]

🚀 Overview

This PR adds a plug-and-play interactive web interface that allows users to learn and test all 33 JavaScript concepts in a live environment on their own local server. Users can now select concepts from an organized list, write and execute code in a live editor, and see real-time console output.

🎯 What's New

Interactive Learning Platform

• Live Code Editor: Write and execute JavaScript code directly in the browser
• 33 Concept Library: Each concept includes comprehensive descriptions and working code examples
• Real-time Console Output: See logs, errors, and results instantly
• Smart Search: Quickly find concepts with real-time filtering
• Responsive Design: Works seamlessly on desktop, tablet, and mobile devices

Quick Start

# Clone and navigate to the repository
git clone https://github.com/leonardomso/33-js-concepts.git
cd 33-js-concepts

# Start the server
node server.js
# or
npm start

# Open your browser
# Navigate to http://localhost:3000

🏗️ Technical Implementation

Files Added

• public/index.html - Main interface (65 lines)
• public/styles.css - Responsive styling (357 lines)
• public/app.js - Core application logic (239 lines)
• public/concepts-data.js - All 33 concepts with examples (1,835 lines)
