Can you explain what generations of garbage collection exist in managed languages?

In managed languages such as Dart (used in Flutter), garbage collection is typically organized into generations to optimize performance.

Main generations:

• Young Generation: this is where newly created objects are placed. Garbage collection occurs frequently here, as many objects quickly become unnecessary.

• Old Generation: objects that have survived several collection cycles in the young generation are moved here. Collection occurs less frequently here, as objects are considered long-lived.

• Sometimes a Permanent Generation or metadata is distinguished, but in Dart, this is not explicitly expressed.

This approach allows for quick memory freeing of short-lived objects and less resource consumption on long-lived objects.
