A deep technical guide to Async Context and AsyncLocalStorage in JavaScript. Learn how request context propagation works across async boundaries, how runtimes track execution state, and how to avoid parameter drilling in complex backend systems.
A deep technical exploration of Atomics and SharedArrayBuffer in JavaScript. Learn how they enable true parallelism, how memory sharing works across workers, and what it takes to build low-level concurrent systems in the browser and Node.js.
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 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.
