Day 6: JavaScript Dates

Objective

In this challenge, we learn about JavaScript Dates. Check out the attached tutorial for more details.

Task

Given a date string, dateString, in the format MM/DD/YYYY, find and return the day name for that date. Each day name must be one of the following strings: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, or Saturday. For example, the day name for the date 12/07/2016 is Wednesday.

Input Format

Locked stub code in the editor reads the following input from stdin:
The first line contains an integer, d, denoting the number of dates to check.
Each line i of the d subsequent lines contains a date in MM/DD/YYYY format; each date denotes some dateString that is passed to the function.

Constraints

  • It is guaranteed that the input only consists of valid dates.

Output Format

The function must return a string denoting the day of the week corresponding to the date denoted by dateString.

The function is called for the following d = 2 dates:

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

    

    var day_names = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]

    var date = new Date(dateString);
    dayName = day_names[date.getDay()];
    return dayName;
