In the example above, we first import the startOfWeek() function from the date-fns package. We then get the current date using new Date(). Finally, we use the startOfWeek() function to get the start of the week for the given date and log it to the console.

The startOfWeek() function can also take an optional options object as its second argument. The options object can be used to customize the start of the week. For example, to start the week on Monday instead of Sunday, you can pass the following options object:

const startOfWeekMonday = startOfWeek(date, { weekStartsOn: 1 })
