Answer 1

function isYesterdayDate(date : Date) {
  	const yesterday = new Date();
  	yesterday.setDate(yesterday.getDate() - 1);

  	if (yesterday.toDateString() === date.toDateString()) {
      	return true;
  	}

  	return false;
}

const yesterday = new Date();
yesterday.setDate(yesterday.getDate() - 1);
console.log(isYesterdayDate(yesterday));
