Question 1

When should I use setImmediate()?

Accepted Answer

Use setImmediate() when you want to defer execution until the Event Loop reaches the Check Phase, especially after I/O operations.

Question 2

What is the main difference between process.nextTick() and setImmediate()?

Accepted Answer

process.nextTick() executes before the Event Loop continues, while setImmediate() executes during the Check Phase of the Event Loop.

Question 3

Which executes first: process.nextTick() or setImmediate()?

Accepted Answer

process.nextTick() executes first because Node.js processes the nextTick queue before Event Loop phases.

Question 4

Is process.nextTick() part of the Event Loop?

Accepted Answer

No. It uses a separate queue that is processed before the Event Loop continues.
