Use instructions for the console.log method in node.js

Method description:

Prints a character to the standard output stream and ends with a newline.

Grammar:

console.log([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.log('count: %d', count);

//Output & NBSP; Count: 1234; < br / >
console.log('Hello world');

//Output & NBSP; Hello world. < br / >
console.log('count: %d');

//Output & NBSP; Count: % d; < br / >

Source:

Console.prototype.log = function() {

  this._stdout.write(util.format.apply(this, arguments) + 'n');

};
