</html>

3. JavaScript Starter

// main.js - Your JavaScript playground

console.log("🎉 Welcome to JavaScript Learning!");

// This function will display output in the HTML page
function display(message) {
    const outputDiv = document.getElementById('output');
    if (outputDiv) {
        const paragraph = document.createElement('p');
        paragraph.textContent = message;
        outputDiv.appendChild(paragraph);
    }
    console.log(message);
}

// Test the display function
display("JavaScript environment is ready!");
display("Open browser console (F12) to see more output");

🚨 Common Pitfalls & Solutions

Pitfall Solution
Forgetting semicolons Use ESLint or Prettier
Case sensitivity issues JavaScript is case-sensitive: myVar ≠ myvar
Undefined variables Always declare variables before use
Type confusion Use typeof operator to check types
Infinite loops Always update loop conditions

📊 Progress Tracker

// Copy this to track your progress
const moduleProgress = {
    module: "01 - Getting Started",
    topics: {
        variables: { completed: false, confidence: 0 },
        operators: { completed: false, confidence: 0 },
        controlFlow: { completed: false, confidence: 0 }
    },
    exercises: {
        calculator: { completed: false, score: 0 },
        temperature: { completed: false, score: 0 },
        gradeCalculator: { completed: false, score: 0 }
    },
    quiz: { taken: false, score: 0 },
    
    updateProgress(topic, confidence) {
        if (this.topics[topic]) {
            this.topics[topic].completed = true;
            this.topics[topic].confidence = confidence;
        }
    },
    
    getCompletionPercentage() {
        const totalItems = 3 + 3 + 1; // topics + exercises + quiz
        let completed = 0;
        
        // Count completed topics
        Object.values(this.topics).forEach(t => {
            if (t.completed) completed++;
        });
        
        // Count completed exercises
        Object.values(this.exercises).forEach(e => {
            if (e.completed) completed++;
        });
        
        // Count quiz
        if (this.quiz.taken) completed++;
        
        return Math.round((completed / totalItems) * 100);
    }
};

console.log("Progress tracker initialized. Current completion: 0%");
