To get yesterday’s date with JavaScript, you simply need to get the current date, and then subtract one day from it, like this:
const today = new Date()
const yesterday = new Date(today)
yesterday.setDate(yesterday.getDate() - 1)
today.toDateString()
yesterday.toDateString()
Now try console logging out yesterdays date:
console.log(yesterday.toDateString())
Nice and simple!
