Just published a deep dive on one of the most misunderstood topics in JavaScript: “JavaScript Is Single-Threaded… So Why Do Race Conditions Exist?” Most developers assume: single-threaded = no concurrency problems. But modern JavaScript systems constantly deal with: race conditions stale state async timing bugs API overwrites websocket ordering issues synchronization failures Because JavaScript concurrency is really about: ⚡ execution order ⚡ async scheduling ⚡ overlapping operations —not multiple JavaScript threads. The article explores: Event Loop internals Microtasks vs Macrotasks Promise scheduling async/await execution flow Node.js Event Loop phases libuv & thread pools process.nextTick() Worker Threads real production synchronization bugs One realization changed how I think about software engineering: Large-scale systems fail more from coordination problems than syntax problems.…
