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.
The JavaScript event loop isn’t as simple as the diagrams suggest. This deep dive explores microtasks vs macrotasks, rendering phases, task prioritization, Node.js differences, and why your mental model of async execution is probably incomplete.
JavaScript concurrency isn’t true parallelism—and misunderstanding it leads to subtle performance bugs. This deep dive explores the event loop, microtasks vs macrotasks, async scheduling, Web Workers, and how concurrency really works in browsers and Node.js.
