Week 2 Day 4 – Smart Number Analyzer

Project Overview

This project is an advanced version of the Number Analyzer app. It uses functions and event handling to create a modular and maintainable JavaScript application.

Features

• Modular code using functions
• Even, Odd, and Prime detection
• Dynamic UI update
• Clean and reusable logic

Tech Stack

• HTML5
• CSS3
• JavaScript

How It Works

1. User enters a number

2. Clicks Analyze

3. handleAnalyze() triggers

4. generateAnalysis() runs loop

5. Helper functions:

   • isEven()
   • isPrime()

6. Output displayed on UI

Key Concepts Used

• Functions
• Parameters & return values
• Event handling
• Code modularization
• Nested logic

Output Example

Input: 5

1 - Odd 2 - Even | Prime 3 - Odd | Prime 4 - Even 5 - Odd | Prime

Total Even Numbers: 2 Total Odd Numbers: 3 Total Prime Numbers: 3

Future Improvements

• Optimize prime logic (√n)
• Add UI enhancements
• Add reset button
• Add animations

Learning Outcome

• Writing clean, structured code
• Breaking problems into functions
• Understanding event-driven programming
