Fibonacci Calculator
A web application that calculates Fibonacci numbers without freezing processes.
What is this?
This is a Fibonacci number calculator that stays responsive even when calculating large numbers. Instead of making you wait and stare at a frozen screen, it gives you instant feedback and works in the background.
How does it work?
The Problem
Some Fibonacci numbers take time to calculate. Without smart design, your browser would freeze and show nothing until the calculation finishes.
Our Solution
We built a system that can say: "Got your request! We're working on it - check back in a moment."
Here's what happens when you ask for a Fibonacci number:
- You submit a request -> The app immediately responds "We're calculating this for you!"
- Background calculation -> A worker starts computing the number behind the scenes
- On check request -> The app shows your result or "We're still calculating this for you!"
- Smart caching -> If someone else asks for the same number, we give the answer instantly
Why this matters
- No frozen screens - You always get immediate feedback
- Shared calculations - If multiple people ask for the same number, we calculate it once
- Popular numbers - See which Fibonacci numbers people request most
- Fast results - Previously calculated numbers appear instantly

Important Note
This is a demonstration project to showcase async processing patterns. While we use Fibonacci numbers as an example, the same architectural approach can be applied to many real-world scenarios:
Practical Use Cases
- Image/Video Processing - Upload a file, get immediate confirmation, process in background
- Report Generation - Request a complex report, receive "generating..." status, get notified when ready
- Email Campaigns - Queue bulk email sends, show progress, handle bounces asynchronously
- Machine Learning - Train models in background while users continue working
- Backup Operations - Initiate backups, show status, notify on completion
- Many more
The key principle: Never make users wait for slow operations. Always provide immediate feedback and handle the work asynchronously.
