Last Updated : 31 Mar, 2021

The console. groupEnd() method is an inbuilt application programming interface of the console module which is used to end the started group by calling method console.group() or console.groupCollapsed(). It indicates the end of a message group.

Syntax:

console.groupEnd();

Parameters: This method doesn’t accept any parameter.

Return Value: This method doesn’t return anything but ends the group on the console.

Below examples illustrate the use of console. groupEnd() method in Node.js.

Example 1:

index.js

// Node.js program to demonstrate the  
// console.groupEnd() method  
  
// This code example demonstrate the method 
// with console.groupCollapsed() method 
  
// Accessing console module  
const console = require('console'); 
  
console.log("GeeksforGeeks"); 
console.log(); 
  
console.groupCollapsed(); 
  
// Printing First line of Group  
console.log("1st print from the first Collapsed group"); 
  
// Printing Second line  of Group 
console.log("2nd print from the first Collapsed group"); 
  
// Calling the groupEnd() method 
console.groupEnd(); 
console.log(); 
  
// Printing out of the group 
console.log("GeeksforGeeks after the Ending of the group"); 
console.log(); 

Run index.js file using below command:

node index.js

Console Output:

GeeksforGeeks

  1st print from the first Collapsed group
  2nd print from the first Collapsed group

GeeksforGeeks after the Ending of the group

Example 2:

index.js

// Node.js program to demonstrate the  
// console.group() method  
  
// This code example demonstrate the 
// method with console.group() method 
  
// Accessing console module  
const console = require('console'); 
  
console.log("GeeksforGeeks "); 
console.log("================================"); 
console.log(); 
  
// Creating main group 
console.group("This is the starting main group"); 
console.log(); 
  
// Printing First line of group  
console.log("1st group and not from any nested group"); 
console.log(); 
  
// Creating first nested group inside main group 
console.group("Starting of the 1st Nested group"); 
  
// Printing 1st line  
console.log("Hello Geeks for Geeks from "
    + "1st Main Nested group"); 
  
// Printing 2nd line  
console.log("Computer Science Portal(Geeks for "
    + "Geeks) from 1st Main Nested group"); 
  
// Ending of the first nested group 
// Calling the groupEnd() method 
console.groupEnd(); 
  
console.log(); 
console.log(); 
  
// Creating second nested group  
console.group("Starting of the 2nd Main Nested group"); 
  
// Printing 1st line 
console.log("Hello from 2nd Main Nested group"); 
  
// Printing 2nd line  
console.log("Hello from 2nd Main Nested group"); 
  
// Ending of the first nested group 
// calling the groupEnd() method 
console.groupEnd(); 
  
console.log(); 
  
// Printing last line of the group 
console.log("Now Main group will end"); 
  
  
console.log(); 
  
// Calling groupEnd() method (It is used to  
// end the group for more understanding 
// the group method)  
// Calling the groupEnd() method 
console.groupEnd(); 
  
// Printing from outside the Main group 
console.log("This the Hello from GeeksforGeeks"
    + " from outside the Main Group"); 
  
console.log(); 
console.log("==================================="); 

Console Output:

GeeksforGeeks 
================================

This is the starting main group

  1st group and not from any nested group

  Starting of the 1st Nested group
    Hello Geeks for Geeks from 1st Main Nested group
    Computer Science Portal(Geeks for Geeks) 
    from 1st Main Nested group


  Starting of the 2nd Main Nested group
    Hello from 2nd Main Nested group
    Hello from 2nd Main Nested group

  Now Main group will end

This the Hello from GeeksforGeeks from outside the Main Group
