Generational Garbage Collection

Generational Garbage Collection is an efficient memory management technique used in programming languages. It categorizes objects based on their lifespan: new objects (young generation), objects that persist longer (old generation), and sometimes an in-between area. Since most objects die young, the system frequently cleans up the young generation quickly, freeing memory for new objects. Objects that survive multiple collections are promoted to the old generation, which is cleaned less often. This approach improves performance by focusing cleanup efforts where they are most needed, reducing the time spent tracing all objects and making programs run more efficiently.
