The console.countReset() method is an inbuilt application programming interface of the console module which is used to reset the count for the specific label passed to it as a parameter. Syntax:

console.countReset( label );

Parameters: This method has one parameter as mentioned above and described below:

label: It is an optional parameter that specifies the label whose counter to be reset. Default value is "default".

Return Value: This method does not provide any output but reset the counter for the specified label. Below examples illustrate the use of console.countReset() method in Node.js: Example 1:

javascript

// Node.js program to demonstrate the 
// console.countReset() method

// Accessing console module
const console = require('console');
 
// Calling console.count() method 
console.count("a");
console.count("b");
console.count("a");
console.count("a");
console.count("a");
console.count("b");
 
// Resetting counter
console.countReset("a");
console.countReset("b");
 
console.count("a");
console.count("b");

Output:

a: 1
b: 1
a: 2
a: 3
a: 4
b: 2
a: 1
b: 1

Example 2:

javascript

// Node.js program to demonstrate the 
// console.countReset() method

// Accessing console module
const console = require('console');

// Calling console.count() method
// with no parameter to count
// default label
console.count();
console.count("a");
console.count("b");
console.count("a");
console.count("a");
console.count();
console.count();

// Resetting counter
console.countReset();
console.countReset("a");
console.countReset("b");

console.count();
console.count("a");
console.count("b");

Output:

default: 1
a: 1
b: 1
a: 2
a: 3
default: 2
default: 3
default: 1
a: 1
b: 1

Note: The above program will compile and run by using the node filename.js command. Reference: https://nodejs.org/api/console.html#console_console_countreset_label
