Heap Memory
Provides dynamically allocated storage whose lifetime is independent of one call frame
Why learn Heap Memory?
It supports variable-size and shared object graphs
The problem it solves
It retains runtime data beyond a function's stack frame
Where it came from
Heap Memory is a programming language and runtime concept that provides dynamically allocated storage whose lifetime is independent of one call frame. Its guarantees and tradeoffs depend on the concrete implementation and operating context.
