let currentDate = lastDate;
currentDate = new Date(currentDate.setDate(currentDate.getDate() + diffDays));
I only updated the value of currentDate, but why did the value of lastDate also change when I set the date for currentDate?
let currentDate = lastDate;
currentDate = new Date(currentDate.setDate(currentDate.getDate() + diffDays));
I only updated the value of currentDate, but why did the value of lastDate also change when I set the date for currentDate?
Do you mind swapping out var currrentdate = lastDate; with
var currrentdate = new Date(lastDate);The revised line should function correctly.
