Advanced Python - Memory Management

Understand how variables live in the memory heap as objects occupying slots, with binary addresses managed by the JavaScript memory manager across engines like V8 and SpiderMonkey.

Explore how Python memory management allocates memory and prints physical addresses for variables. See how immutable strings produce new memory addresses, while shared references reveal underlying memory behavior.

Discover how reference counting tracks references to memory in JavaScript, why primitives are immutable, how mutable arrays and objects share memory addresses, and how naive garbage collection frees unreferenced objects.

Explore reference counting in code, illustrating how assigning variables increases memory references and how objects are garbage-collected when references drop to zero in Python.

Examine how reference counts drop to zero and objects are freed, and how circular references prevent destruction, leaving objects in memory and causing memory leaks.
