A deep technical breakdown of how async/await works under the hood. Learn how V8 transforms your code into a state machine, how promises and microtasks interact with the event loop, and what this means for performance and debugging.
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 dive into the real cost model of abstraction in JavaScript. Explore runtime overhead, hidden allocations, bundle size impact, de-optimizations in V8, cognitive load, and how abstraction choices affect performance and long-term maintainability.
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.
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.
