In certain scenarios, it becomes necessary to convert object properties that are undefined to null. This is particularly relevant in the case of Next.js, where getStaticProps or getServerSideProps must not return undefined properties. Returning an undefined property results in a runtime error. However, manually checking for possibly undefined properties is error-prone and can lead to oversights if the object changes.
