As we all seen JavaScript is the most preferred programming language of the Internet.
Here are someuseful functions to iterate through the weeks / months / quarters in your code using simple JS functions.
const weekRange = (num) => {
// num defintion: -1 is pevious week, likewise -2,-3 OR only 1, 2 for upcoming weeks.
let mydate = new Date();
let mydate2 = new Date();
num = num * 7; // 7 days per week * counter
let x = mydate.getDate() - mydate.getDay() + 1; // +1 to set the first day of the week as Monday
mydate.setDate(x + num);
mydate.setHours(0, 0, 0); // setting the 0,0,0 to cover entire week right from day one midnight
mydate2.setDate(x + num + 5 + 1); // +6 to calculatethe Saturday EOD
mydate2.setHours(23, 59, 0); // setting 23,59 tp cover last day of the week till midnight
return [mydate, mydate2]; //return array to compare the window with
};

"January",
"February",

return DateObj;
};

let qstart = new Date();
let qend = new Date();
let quarter = "";
num = parseInt(num);
if (num !== 0) {
