What is the difference between setImmediate() and setTimeout() in NodeJS?

setImmediate():

setImmediate Executes immediately after the current event loop iteration, making it ideal for time-sensitive tasks without delay. It has higher priority than other I/O events and timers, potentially causing starvation of other tasks due to its immediate execution.

setTimeout():

Executes after a specified delay (in milliseconds), making it suitable for implementing delays or timeouts in code. It has a lower priority compared to setImmediate(), reducing the likelihood of starving other tasks in the event loop.

Difference between setImmediate() and setTimeout() in NodeJS:

setImmediate()	setTimeout()
Executes immediately after the current event loop iteration	Executes after a specified delay (in milliseconds)
Has higher priority than other I/O events and timers	Has lower priority compared to setImmediate()
Useful for executing code immediately after the current I/O operation or in the same event loop iteration	Useful for delaying the execution of code for a specific duration
Executes after I/O callbacks but before any timers	Executes after all I/O callbacks and some timers
Can cause starving of other tasks due to higher priority	Less likely to starve other tasks due to lower priority
Ideal for executing time-sensitive code without delay	Ideal for implementing delays or timeouts in code
