const date = new Date('2022-10-10');

In the above example, we first import the lastDayOfWeek function from the date-fns library. Then, we create a new Date object with a specific date (in this case, 10th October 2022). Finally, we call the lastDayOfWeek function with the date object and an options object that specifies which day of the week is considered the start of the week (in this case, Monday). The function returns the last day of the week for the given date (in this case, 16th October 2022).
