Make memory behavior completely visible: references, lifecycles, garbage collection, diffs, and lifetime ownership.
Track how references are created, updated, and removed over time.
Follow an object from creation through mutation, sharing, and destruction.
const user = { name: 'Alice', age: 30 };A new object is allocated on the heap. The variable 'user' holds a reference to it.
Visualize the mark-and-sweep algorithm that reclaims unused memory.
Compare heap snapshots to instantly see what changed.
Understand object age, reference counts, and ownership chains.
