In this example, the getWeeksInMonth function is imported from the date-fns package. We create a new Date object for the month we want to get the number of weeks for. Then, we pass the date object as an argument to the getWeeksInMonth function and assign the result to the weeksInMonth variable. Finally, we log the result to the console using console.log.
