What is Lazy Loading?

Lazy loading is a design pattern used in software development to improve performance and reduce resource consumption. It involves postponing the initialization or loading of an object until it is needed.

More About Lazy Loading

You can apply lazy loading to classes, images, videos, and other types of objects. When you use lazy loading for class objects, the class definition is loaded only when an instance of the class is first created.

For images and videos, the content is not downloaded until the user requires it. This setting can minimize bandwidth consumption and improve page load times.

However, lazy loading is not without its drawbacks. One potential problem is that if an object is never used, it will never be initialized. Thus its resources will never be freed. This can lead to memory leaks. Another issue is that lazy loading can introduce delays when an object is first used.
