node.js: console.groupEnd(): Decreases the indentation while logging

console.groupEnd()
Decreases indentation of subsequent lines by two spaces.

HelloWorld.js
console.group("User '%s' login failed", "Krishna");
console.group("Please retry after some time");
console.group("If you forgot the password, please retry");

console.groupEnd();
console.log("\nCalling groupEnd first time");
console.log("Good Morning");
console.log("Have a nice day");
console.log("Welocme to node.js programming");

console.groupEnd();
console.log("\nCalling groupEnd second time");
console.log("Good Morning");
console.log("Have a nice day");
console.log("Welocme to node.js programming");

console.groupEnd();
console.log("\nCalling groupEnd third time");
console.log("Good Morning");
console.log("Have a nice day");
console.log("Welocme to node.js programming");

console.groupEnd();
console.log("\nCalling groupEnd fourth time");
console.log("Good Morning");
console.log("Have a nice day");
console.log("Welocme to node.js programming");
