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 release in 2015, it has become one of the most popular development environments, supporting hundreds of programming languages through its rich extension ecosystem and built-in features like IntelliSense, debugging, Git integration, and customizable workspaces. The key to mastering VS Code lies in understanding its keyboard shortcuts, command palette, and multi-cursor editing—which together enable developers to write, navigate, and refactor code far faster than mouse-driven workflows allow.
