I have done it on console Like this

var days = 7;
nowDate.setDate(nowDate.getDate() - days);
var mamat = nowDate.toISOString().split('T')[0];
console.log(mamat);

Solution 
  • let date = new Date();
date.setDate(date.getDate()-1);
console.log(date.toLocaleDateString());
// Woud log:
// 1/12/2019
console.log(date.toLocaleDateString('fa-IR'));
// Woud log:
// ۱۳۹۷/۱۰/۲۲

    If you want to set the calendar, then you can pass the desired calendar as an argument to the toLocaleDateString method, as per the MDN docs. For example, passing 'ar-EG' will result in Arabic digits.
