Demystifying setTimeout(0): Why This Workaround Masks Architectural Issues

Developers frequently use setTimeout(fn, 0) as a quick fix for race conditions, but this practice actually masks deeper architectural problems with component state synchronization and render lifecycle management. Understanding the JavaScript Event Loop's distinction between microtasks and macrotasks is crucial for writing scalable frontend code. Rather than relying on timer-based hacks, developers should leverage native alternatives like requestAnimationFrame and proper state management frameworks to address root causes.
