VS Code

VS Code has become the default code editor for most software developers because Microsoft got three things right simultaneously: it is fast, free, and has the largest extension ecosystem of any editor. GitHub Copilot integration at $10/month turns it into an AI-assisted coding environment that no comparable free editor matches on breadth or polish. The IntelliSense, debugger, and Git integration are fully built in — the baseline experience before any extensions is already capable by any standard. For developers who want an open-source build without Microsoft telemetry, VSCodium is the alternative; otherwise the question is not which editor to use but how to configure it.
