The date object result gives Friday and undefined

Question

Friday and undefined is the result. Why is it not Friday alone?

function main() {
var year = parseInt(readLine(), 10);
var month = parseInt(readLine(), 10);
var day = parseInt(readLine(), 10);
var daysName = this.day;

console.log(getWeekDay(year, month, day))

}

function getWeekDay(year, month, day) {
var names = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
var d = new Date(year, month, day);
//complete the function
var i = d.getDay();

var daysName = names[i];

console.log(daysName);
}

Answer 1

function getWeekDay isn't returning anything yet you are using console.log on it. Simply call the function otherwise it will print undefined if no value is returned by the function.
