How does this online editor run Visual Studio Code in the browser?

FreePythonCompiler integrates Microsoft Monaco Editor—the exact open-source code editor engine that powers desktop Visual Studio Code. You get the same IntelliSense autocomplete, bracket colorization, find/replace, and syntax highlighting directly in your browser without downloading VS Code.
