Page 5. Modern JavaScript Syntax And Features - Modules with Imports and Exports
First code block

In the code example, a named export is mistakenly imported as if it were the default export. To correctly import a named export, one should use curly brackets, as demonstrated below:

```
// Filename: staff.mjs
// =========================================
export const baker = { bake(item) {} };

// Filename: cakeFactory.mjs
// =========================================
import { baker } from "/modules/staff.mjs";
```

Also in the code example, named export of `cakeFactory` was not shown which may cause confusion.
