This choice is pedagogical. SQL, with its rigid schemas, joins, and normalization rules, often presents a steep cognitive load for beginners who are still grappling with JavaScript promises. MongoDB, with its JSON-like document structure, offers a familiar syntax for JavaScript developers. However, Jonas does not teach it lazily. He navigates the complexities of Mongoose, explaining the intricacies of middleware, validation, and embedding versus referencing documents. MongoDB, with its JSON-like document structure, offers a
