GitHub Copilot

GitHub Copilot is an AI-powered code completion tool developed by GitHub in collaboration with OpenAI. It integrates into popular editors like VS Code and JetBrains IDEs, providing real-time code suggestions as developers type, based on context from the current file and related code.

Copilot capabilities include: multi-line code completions, function implementation from comments or signatures, test generation, code explanations via chat, and support for dozens of programming languages. It learns from the context of your project to provide more relevant suggestions.

Copilot has become one of the most widely adopted AI coding tools, making familiarity with it valuable for modern engineers. Effective use involves: knowing when to accept, modify, or reject suggestions, writing clear comments to guide generation, reviewing suggested code carefully, and understanding that Copilot works best for common patterns rather than novel logic.
