The startOfMonth function takes a Date object as input and returns the start of the month. In the example above, startOfMonth will be the first day of the current month based on the today object. When you run the code above, startOfMonth will be logged in the console.

It's important to note that the startOfMonth function does not modify the original Date object passed as input, it returns a new Date object with the start of the month.
