Collecting random year from Random Date

So I have generated a random date from two dates

var dateOfInterest =  function randomDate(start, end) {
    return new Date(start.getTime() + Math.random() * (end.getTime() - start.getTime()));
}

randomDate(new Date(2012, 0, 1), new Date());

Now I need to collect the year of the random date generated with the code:

var yearOfInterest = dateOfInterest.getFullYear();

This does not work. I would appreciate the assistance. Thank you.

Answer

A function definition does not need the var, just assign the function itself, then call it to receive the return value.

I’ve placed the getFullYear in the function after creating a new Date and changed the function name to a more describing one: getRandomYearBetweenDates

function getRandomYearBetweenDates(start, end) {
    return new Date(start.getTime() + Math.random() * (end.getTime() - start.getTime())).getFullYear();
}

const res = getRandomYearBetweenDates(new Date(2012, 0, 1), new Date());
console.log(res);
