Hi there! Thank you for your question. The purpose of creating a custom lazy-loading directive in Angular is to have more control over the loading process. While Angular does offer native lazy loading support, creating a custom directive can provide you with the flexibility to customize the lazy-loading behavior according to your specific needs.

By implementing your own directive, you can tailor the loading logic to suit your application's requirements. This can include adding additional features, optimizing for performance, or even integrating with third-party libraries or services that may not be directly supported by Angular's built-in lazy loading.

In summary, while Angular does provide native support for lazy loading, creating a custom directive allows you to take more control over the loading process and adapt it to your project's unique demands. If you have any more questions or need further clarification, feel free to ask!
