JavaScript Code Daily Challenge #1


This is a series of JavaScript Code Daily Challenge. Each day I show a few solutions written in JavaScript. The questions are from coding practice/contest sites such as HackerRank, LeetCode, Codeforces, Atcoder and etc.

Day 1: Hello, World

'use strict';


let inputString = '';
let currentLine = 0;

process.stdin.on('data', inputStdin => {
    inputString += inputStdin;

process.stdin.on('end', _ => {
    inputString = inputString.trim().split('\n').map(string => {
        return string.trim();


function readLine() {
    return inputString[currentLine++];
Enter fullscreen mode Exit fullscreen mode

Function need to be change

function greeting(parameterVariable) {
    console.log('Hello, World!');
Enter fullscreen mode Exit fullscreen mode
function main() {
    const parameterVariable = readLine();

Enter fullscreen mode Exit fullscreen mode
