Modernizing legacy code with GitHub Copilot: Tips and examples

Legacy code, often written in outdated languages like COBOL, presents significant challenges for modernization due to technical debt, integration issues, and a shortage of knowledgeable developers. GitHub Copilot, an AI-powered coding tool, aids in this process by providing intelligent code completions, test generation, and refactoring suggestions, streamlining the transition from legacy systems to modern ones like Node.js. It allows developers to maintain their workflow within integrated development environments (IDEs) such as VS Code without the constant need for external resources like Google or Stack Overflow. This tool is especially useful for navigating complex legacy codebases and addressing common obstacles such as data migration, compatibility, cost, and security vulnerabilities. GitHub Copilot offers features across different tiers, including a free tier, enabling developers to utilize its capabilities for various tasks, ultimately enhancing productivity and facilitating the modernization of legacy systems.
