Well, first you get the date at the current time (today), then you subtract a day from it:

const today = new Date()
const yesterday = new Date(today)

yesterday.setDate(yesterday.getDate() - 1)

today.toDateString()
yesterday.toDateString()

We use the setDate() method on yesterday, passing as parameter the current day minus one.

Even if it’s day 1 of the month, JavaScript is logical enough and it will point to the last day of the previous month.
