Structural Design Patterns in Modern C++ - Pros and Cons - Flyweight Design Pattern

The lecture covers the Flyweight design pattern, which helps reduce memory usage by sharing common parts of objects. It is beneficial when dealing with a large number of fine-grained objects, but it may introduce runtime costs related to managing extrinsic state. The pattern is suitable when object identity is not crucial, and some state can be shared. The decision to use Flyweight should consider the application's memory needs and the cost of storage.
