🚀 Difference Between process.nextTick() and Promise.resolve().then() in Node.js Both are used to schedule microtasks but differ in execution priority and behavior. ⚡ 🔥 Key Differences: ✅ process.nextTick() Executes immediately after the current operation, before any I/O or timers. Blocks the event loop if used excessively. Higher priority than Promise.resolve().then(). ✅ Promise.resolve().then() Runs in the next microtask queue, after process.nextTick(). Non-blocking and optimized for asynchronous workflows. Used in both Node.js and browsers. 💡 Use process.nextTick() for critical, immediate execution and Promise.resolve().then() for standard async operations! 🎉 #NodeJS #AsyncProgramming #Microtasks 🚀 #EventLoop #Promises #WebDevelopment #BackendDev #JavaScript #CodingTips #DeveloperLife 💻✨
