var dateStrings = Array(10000).fill(null).map(() => (new Date()).toISOString());var padDate = date => (date < 10 ? `0${date}` : date);

Tests:

Parse Date

dateStrings.map((d) => {
  const date = new Date(d);
  return `${padDate(date.getDate())}.${padDate(date.getMonth() + 1)}.${padDate(date.getYear())}`;
});

 
dateStrings.map((d) => {  const date = new Date(d);  return `${padDate(date.getDate())}.${padDate(date.getMonth() + 1)}.${padDate(date.getYear())}`;});

String split
dateStrings.map((d) => { const [year, month, date] = d.split('-'); return `${date}.${month}.${year}`; });
dateStrings.map((d) => {
const [year, month, date] = d.split('-');
return `${date}.${month}.${year}`;
});
