Solution - Day 0: Hello, World - Hacker Rank Solution
JavaScript
'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 greeting(parameterVariable) {
// This line prints 'Hello, World!' to the console:
console.log('Hello, World!');
console.log(parameterVariable)
// Write a line of code that prints parameterVariable to stdout using console.log:
