How Heap Allocation and Garbage Collection works

An interactive concept flow for heap allocation and garbage collection, from its assumptions through the main operation and boundary checks.

readyThe heap holds objects whose lifetimes are not tied to one simple lexical scope. A runtime allocator reserves space, initializes an object, and returns a reference. Garbage collection reclaims memory that is no longer reachable under the collector’s object graph and root rules.

Use the stages in order to explain heap allocation and garbage collection. Each stage makes one assumption visible: what the operation promises, what representation it uses, how state changes, which boundary can invalidate a shortcut, and what evidence confirms the result.
