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
