Memory Explained - Why Your Code Crashes (Stack vs Heap)

Ever passed a list to a function and it changed without you touching it? That's not a bug — that's how memory works.

In this video, I break down the two regions of memory: the stack and the heap. You'll learn why stack overflows happen, how memory leaks occur even with garbage collection, and why your data sometimes mutates unexpectedly.

This isn't abstract theory — these are the concepts that explain real bugs you've probably encountered.

What you'll learn:
How the stack works
Why stack overflows happen
What the heap
Pass by value vs pass by reference
Memory leaks in garbage-collected languages
