Call Stack vs. Heap: Master Node.js Memory & Stop Stack Overflow

Tired of mysterious crashes and those dreaded "Stack Overflow" errors? It's time to master memory management! We pull back the curtain on the two most fundamental systems in every Node.js app: The Call Stack and The Heap.

Understanding this "tale of two co-workers" is the key to writing highly efficient, leak-free JavaScript code.

Here’s the Memory Management Blueprint (with timestamps):

The Meticulous Manager (Call Stack): The fast, LIFO structure that tracks function calls and why its fixed, tiny size (1MB) leads to the Stack Overflow error [01:10].

The Massive Warehouse (The Heap): The dynamic, flexible space where all your complex data (objects, arrays, large strings) is stored for the long haul [02:28].

The Partnership Secret: How the Stack and Heap work together using tiny Pointers to manage massive data efficiently [03:48].

3 Classic Memory Leaks: Spot the mistakes that cause your app to bloat and slow down:

Accidental Global Variables [05:15]

Forgotten Intervals [05:36]

Heavy Closures holding onto massive arrays [05:54]

Pro-Level Optimization: Practical tips on optimizing closures and using Node.js Streams for huge files to keep your memory lean and mean [06:19].
