Mini Code Snippet Library for Payment Processing

A lightweight collection of JavaScript and Python code snippets demonstrating common payment processing tasks without external libraries.

---

📘 Overview

This library simulates three essential payment operations for e-commerce systems:

• Payment Authorization
• Payment Capture
• Refund Processing

Each snippet shows the basic flow of how payment systems handle transactions — useful for testing logic or learning payment flow concepts.

🧩 Snippets Overview

Function	Language	Description
authorizePayment() / authorize_payment()	JS / Python	Simulates payment authorization
capturePayment() / capture_payment()	JS / Python	Simulates payment capture after authorization
processRefund() / process_refund()	JS / Python	Simulates refund processing

---

🧪 Example Output

Running the demo prints something like:

Authorization: { status: 'authorized', amount: 100, transactionId: 123456 }
Capture: { status: 'captured', transactionId: 123456, capturedAmount: 100 }
Refund: { status: 'refunded', transactionId: 123456, refundAmount: 50 }
