Below examples illustrate the use of console.countReset() method in Node.js:
Example 1:
// 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:
// 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.
