Check if a date is between two other dates

• Use the greater than operator (>) to check if the date comes after the dateStart.
• Use the less than operator (<) to check if the date comes before the dateEnd.
• Use the logical and operator (&&) to check if the date is between the dateStart and the dateEnd.

const isBetweenDates = (dateStart, dateEnd, date) => date > dateStart && date < dateEnd;

isBetweenDates(new Date(2010, 11, 20), new Date(2010, 11, 30), new Date(2010, 11, 19)); // false
isBetweenDates(new Date(2010, 11, 20), new Date(2010, 11, 30), new Date(2010, 11, 25)); // true
isBetweenDates(new Date(2010, 11, 20), new Date(2010, 11, 30), new Date(2010, 11, 31)); // false
