More FAQs in Difference Between process.nextTick() and setImmediate() in Node.js
process.nextTick() executes first because Node.js processes the nextTick queue before Event Loop phases.
No. It uses a separate queue that is processed before the Event Loop continues.
Use setImmediate() when you want to defer execution until the Event Loop reaches the Check Phase, especially after I/O operations.
