In a non-module script, this is the global object (window in browsers). In ES modules, top-level this is undefined. In Node.js CommonJS, top-level this is module.exports.
To prevent accidental global pollution. ES modules are designed to be isolated. If you need the global object, use globalThis explicitly.
