If you want to get the current date in the format of yyyy-mm-dd using Javascript you can do:
new Date().toISOString().split('T')[0];
Where new Date() gets the date as :
Fri Mar 11 2022 11:04:44 GMT+0200 (Eastern European Standard Time) {}
.toISOString() convert it to: 2022-03-11T09:03:38.056Z
and as we need only the date, we split it and get the first part by: .split(‘T’)[0]
