  Single Page Applications (SPAs) are uniquely susceptible to catastrophic memory degradation. Unlike traditional multi-page applications that clear the execution environment on every navigation, SPAs persist a single JavaScript execution context for hours or even days. Over time, unhandled object references and lingering event listeners silently consume JS heap space, resulting in severe frame drops, unresponsive interfaces, and eventual "Aw, Snap!" browser crashes. Locating a Chrome DevTools memory leak is notoriously difficult because garbage collection (GC) failures do not throw exceptions. To restore stability and achieve baseline SPA performance optimization, engineers must shift from inspecting network payloads to analyzing the V8 engine's memory heap directly. The Root Cause: Why V8 Fails to Sweep The V8 JavaScript engine handles memory allocation automatically using a Mark-and-Sweep garbage collection algorithm. The garbage collector traverses the memory graph st...
