 You can specify which of these modes your code is intended to run in by specifying the `sourceType` property. This property can be set to `"module"`, `"commonjs"`, or `"script"`. By default, `sourceType` is set to `"module"` for `.js` and `.mjs` files and is set to `"commonjs"` for `.cjs` files. Here's an example:
