JavaScript Datetime: Exercise-54 with Solution

Write a JavaScript function to check if a given date is between two other dates.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2
// Define a function isBetweenDates that takes three Date objects as parameters: dateStart, dateEnd, and date
const isBetweenDates = (dateStart, dateEnd, date) =>
  // Check if the provided date falls between the start and end dates
  date > dateStart && date < dateEnd;

// Log the result of isBetweenDates with specific dates provided as arguments
console.log(isBetweenDates(
  new Date(2010, 11, 20), // December 20, 2010 (start date)
  new Date(2010, 11, 30), // December 30, 2010 (end date)
  new Date(2010, 11, 19)  // December 19, 2010 (date to check)
));
console.log(isBetweenDates(
  new Date(2010, 11, 20), // December 20, 2010 (start date)
  new Date(2010, 11, 30), // December 30, 2010 (end date)
  new Date(2010, 11, 25)  // December 25, 2010 (date to check)
));

Output:

false
true

Explanation:

In the exercise above,

The code defines a function "isBetweenDates()" that takes three Date objects: "dateStart", "dateEnd", and "date". It checks if the provided 'date' falls between 'dateStart' and 'dateEnd' by comparing them using logical operators. The function returns 'true' if the 'date' is greater than 'dateStart' and less than 'dateEnd', indicating that it lies within the specified range. The code then tests this function with specific dates and logs the results to the console.
