Finding the nth day from today - JavaScript (JS Date)

We are required to write a JavaScript function that takes in a number n as the only input.

For example −

If today is Monday and n = 2,

Then the output should be −

const num = 15; const findNthDay = num => {    const weekday=new Array(7);    weekday[1]="Monday";    weekday[2]="Tuesday";    weekday[3]="Wednesday";    weekday[4]="Thursday";    weekday[5]="Friday";    weekday[6]="Saturday";    weekday[7]="Sunday"    const day = new Date().getDay();    const daysFromNow = num % 7;    return weekday[(day + daysFromNow) % 7]; }; console.log(findNthDay(num));

Output

Following is the output in the console −
