A deep dive into JavaScript’s WeakRef and FinalizationRegistry. Learn how they interact with garbage collection, when they’re useful, why they’re dangerous, and how to reason about memory-sensitive architectures in modern JS runtimes.
A deep technical exploration of memory management in long-lived JavaScript applications. Learn how garbage collection works in V8, how memory leaks happen in browsers and Node.js, and how to design systems that remain stable under sustained load.
Garbage collection doesn’t prevent memory leaks in React apps. This deep dive explores how closures, stale effects, retained references, event listeners, and improper cleanup cause leaks—and how to design components that stay memory-safe at scale.
A deep dive into how V8 executes your JavaScript—covering parsing, hidden classes, inline caching, JIT compilation, de-optimizations, and garbage collection. Learn how understanding the engine changes how you write high-performance code.
