JavaScript Code Daily Challenge #1

About

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
https://www.hackerrank.com/challenges/js10-hello-world/problem

'use strict';

process.stdin.resume();
process.stdin.setEncoding('utf-8');

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();
    });

    main();    
});

function readLine() {
    return inputString[currentLine++];
}

Function need to be change

function greeting(parameterVariable) {
    console.log('Hello, World!');
    console.log(parameterVariable)
}

function main() {
    const parameterVariable = readLine();

    greeting(parameterVariable);
}
