Mastering Node.js Memory: How V8 Manages Heap, Garbage Collection, and Leak Detection
This article explains Node.js memory architecture, how the V8 engine allocates and frees memory across code, stack, and heap, demonstrates using process.memoryUsage() to monitor RSS, heapTotal and heapUsed, describes V8’s Scavenge and Mark‑Sweep garbage collectors, and provides practical techniques for detecting and debugging memory leaks with heap snapshots and profiling tools.
