A comprehensive learning repository for exploring GitHub Copilot features and best practices for AI-assisted coding across multiple programming languages and scenarios.
This repository contains examples, exercises, and demonstrations of GitHub Copilot capabilities organized into focused learning modules. Each folder represents a specific aspect of AI-assisted development, from basic code completion to advanced debugging and documentation generation.
The repository is organized into the following folders (in alphabetical order):
Purpose: Comprehensive collection of GitHub Copilot learning resources and documentation links.
Contents: Curated list of official documentation, tutorials, learning platforms, and community resources for mastering GitHub Copilot.
Purpose: Demonstrates basic code completion and auto-generation capabilities of GitHub Copilot.
Contents: Simple starter files including JavaScript calculator functions, Express server setup, and Python mathematical operations.
Sample Prompt:
// Create a calculator function that adds two numbers
Purpose: Showcases Copilot's ability to explain and document existing code across different programming languages.
Contents: Complex code examples in C# (API retry logic), COBOL (database operations), and TypeScript (Prisma service layer).
Sample Prompt:
Explain this C# async method that handles API retries with exponential backoff or
Document this COBOL program that inserts records into a database
Purpose: Demonstrates code optimization and refactoring suggestions from Copilot.
Contents: Shell script examples that can be improved for better performance and readability.
Sample Prompt:
Refactor this shell script to be more efficient and handle edge cases better" or
Optimize this bash script for better performance
Purpose: Illustrates security vulnerability detection and secure coding practices with Copilot.
Contents: JavaScript code with potential security issues like XSS vulnerabilities in DOM manipulation.
Sample Prompt:
Review this JavaScript function for security vulnerabilities or
Fix the XSS vulnerability in this DOM manipulation code
Purpose: Shows debugging capabilities and error identification assistance.
Contents: Python Flask API with potential issues and malformed JSON response files.
Sample Prompt:
Find and fix the JSON syntax error in this response file or
Help me debug this Flask weather API that's returning errors
Purpose: Demonstrates automatic documentation generation and diagram creation capabilities.
Contents: Mermaid diagram examples showing project timelines and visual documentation.
Sample Prompt:
Create a Mermaid diagram showing the project phases and dependencies that covers the period August 1st 2025 until January 31st 2026. Include 5 Phases each taking 6 weeks, and overlapping equally spaced milestones.
Purpose: Showcases test generation and validation logic creation with Copilot.
Contents: Python validation functions that demonstrate business logic testing scenarios.
Sample Prompt:
/tests Generate unit tests for this price validation function. Validate both success and failure, and include edge cases.
Purpose: Illustrates code review assistance and improvement suggestions.
Contents: Python functions with potential inefficiencies and areas for optimization.
Sample Prompt:
Right Click and Choose Generate Code -> Review
Purpose: Demonstrates Copilot's visual analysis capabilities with images and diagrams.
Contents: Sample images and diagrams for testing vision-based code generation and analysis.
Sample Prompt:
