Description of the console.error method in node.js

Method description:

This method is the same as console.log(), but outputs to the standard error stream.

Grammar:

console.error([data], [...])

Receiving parameters:

Console.log takes several parameters, and if there is only one parameter, it outputs the string form of that parameter.

If there are more than one argument, the output is in a format similar to the C printf() command.

If there are no arguments, only a newline character is printed

Example:

var count = 1234;

console.error('count: %d', count);
