Visual Studio Code (VS Code) is a free, lightweight, and extensible source code editor developed by Microsoft, available on Windows, macOS, and Linux. Since its 2015 release it has grown into the most widely used development environment, with built-in IntelliSense, Git integration, a debugging engine, and a rich extension marketplace. In 2025–2026 GitHub Copilot became a core, built-in feature of VS Code, bringing AI agents, multi-file editing, inline chat, custom agents, and fully autonomous agentic workflows directly into the editor. Mastering VS Code means understanding its keyboard shortcuts, command palette, multi-cursor editing, and the expanding set of Copilot AI features—together enabling developers to write, navigate, refactor, and automate code at a pace that traditional workflows cannot match.
