Check if Date Is Between Two Dates

Introduction

In this lab, we will explore how to check if a date falls between two other dates using JavaScript. We will use the greater than and less than operators to compare the dates and return a boolean value indicating if the date is between the start and end dates. This technique can be useful in various scenarios such as filtering data based on a date range.

Checking if a Date is Between Two Dates

To check if a date is between two other dates, use the greater than (>) and less than (<) operators in JavaScript. Here's an example function:

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

To use this function, pass in the start date, end date, and date to check. The function will return true if the date is between the start and end dates, and false otherwise. Here are some examples:

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
