I need to call an api, passing start and end date, but given that the interval is too wide I am thinking that I need to do several calls using smaller date intervals. This is how I am trying to set start and stop dates:
const daysBracket = 15;
let fromDate = new Date('2020-04-01');
let toDate = new Date('2020-06-01');
let stopDate = new Date('2020-04-01');
while(fromDate <= toDate) {
stopDate.setDate(fromDate.getDate() + (daysBracket - 1));
console.log('Start: ' + fromDate.toDateString());
console.log('Stop: ' + stopDate.toDateString());
console.log('- - - - - - - - - - - - -');
fromDate.setDate(fromDate.getDate() + daysBracket);
}but I am getting this result (start date is updated correctly but stop date doesn't change accordingly):
Start: Wed Apr 01 2020
Stop: Wed Apr 15 2020
- - - - - - - - - - - - -
Start: Thu Apr 16 2020
Stop: Thu Apr 30 2020

Start: Fri May 01 2020

Start: Tue Jun 30 2020

Can you please tell me what I am doing wrong?
I geuss this answer provides some clarity. The following works:
const daysBracket = 15;
let fromDate = new Date('2020-04-01');
let toDate = new Date('2020-06-01');
let stopDate = new Date('2020-04-01');
function addDays(date, days) {
var result = new Date(date);
result.setDate(result.getDate() + days);
return result;
}
while(fromDate <= toDate) {
stopDate = addDays(fromDate, daysBracket -1)
console.log('Start: ' + fromDate.toDateString());
console.log('Stop: ' + stopDate.toDateString());
console.log('- - - - - - - - - - - - -');
fromDate = addDays(fromDate, daysBracket);
}
