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