Node.js FAQ: Top Questions

setTimeout , setImmediate , and process.nextTick are Node.js mechanisms for scheduling asynchronous tasks, differing in timing and event loop phase.

• setTimeout: Schedules a callback after a delay (timers phase).
• setImmediate: Executes a callback after the poll phase (check phase).
• process.nextTick: Runs a callback before the next event loop iteration, higher priority.
• Use Case: Fine-tuning async execution order.
