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 |
