JavaScript's evolution is supported by the V8 JavaScript engine, which includes a critical component: the garbage collector.V8 introduced modern garbage collection techniques based on generational principles in 2008.Generational garbage collection in V8 divides memory into New Space, Old Space, and Large Object Space.V8 uses algorithms like Mark-and-Sweep, Scavenging, and Compaction for memory management.The V8 garbage collector's architecture involves key components like the Heap and Garbage Collection Process.Developers can trigger garbage collection in V8 using global.gc() but it is advised against in performance-critical scenarios.Optimization strategies for V8's garbage collector include managing object lifetimes and memory profiling.Pitfalls like memory leaks and unreleased references can affect the efficiency of the V8 garbage collector.Debugging V8's garbage collector can be done using techniques like Heap Snapshots and Timeline Viewers in Chrome DevTools.Understanding the V8 garbage collector is crucial for optimizing JavaScript applications and ensuring reliable performance.
