sourceMapURL
When the script is compiled from a source that contains a source map magic comment, this property will be set to the URL of the source map.
import vm from 'node:vm';
const script = new vm.Script(`
function myFunc() {}
//# sourceMappingURL=sourcemap.json
`);
console.log(script.sourceMapURL);
// Prints: sourcemap.json
