Create a variable date calculation based on current date in javascript

Question

In Adobe, I've used this to calculate the current date:

var myfield=getField("datebox");

var date=new Date();

date=util.printd("mmm dd yyyy, h:MM tt", date);

myfield.value=date;

I need to be able to take that date and calculate the date X days before.

I am a total newb, appreciate any help.

What I have tried:

I've tried inserting random -7 (for seven days prior), but I'm a total newb, so really I have no idea what to try.

I'm not normally a fan of "black box" solutions, but dates are a pain in the derriere in JS, so I'd recommend using moment.js: https://momentjs.com/

Add days to JavaScript Date - Stack Overflow[^]

JavaScript

Date.prototype.addDays = function(days) {
    var dat = new Date(this.valueOf());
    dat.setDate(dat.getDate() + days);

};
