This function can use printf () to take multiple parameters in a similar way. For example:1 console.log (' Count:%d ', count);If the first string argument is not a formatted string, Util.inspect is applied to each parameter.

Optionally, you can pass parameters to the callback function. The immediate events are placed in the queue in the order in which they were created, and one pops up from the queue header in each iteration of the event loop. This is different from Process.nexttick , which executes the callback function in the
