Solution – Day 6: JavaScript Dates
'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++]; } // The days of the week are: "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" function getDayName(dateString) { let dayName; // Write your code here let dayNames = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]; let date = new Date(dateString); dayName = dayNames[date.getDay()]; return dayName; } function main() { const d = +(readLine()); for (let i = 0; i < d; i++) { const date = readLine(); console.log(getDayName(date)); } }
