# Day 6: JavaScript Dates | 10 Days Of JavaScript | HackerRank Solution

Hello coders, today we are going to solve Day 6: JavaScript Dates HackerRank Solution which is a part of 10 Days of JavaScript Series.

## Objective

In this challenge, we learn about JavaScript Dates.

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 dataString 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.

Sample Input 0

```2
10/11/2009
11/10/2010```

Sample Output 0

```Sunday
Wednesday```

Explanation 0

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

1. The date `10/11/2009` was a Sunday, so we return `Sunday`.
2. The date `11/10/2010` was a Wednesday, so we return `Wednesday`.

## 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();
});

return inputString[currentLine++];
}

// The days of the week are: "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"
function getDayName(dateString) {
let dayName;
let dayNames = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
let date = new Date(dateString);

dayName = dayNames[date.getDay()];

return dayName;
}

function main() {
