Answers for "new ().toisostring().substring(0, 10);"

date().toisostring().slice(0 10) giving wrong result

//Add Z in the end for getting the correct value with local timezone
var a = new Date("June 08, 2018 Z");
var res = a.toISOString().slice(0, 10);
console.log(res);

toLocalIsoString() vs toIsoString()

var tzoffset = (new Date()).getTimezoneOffset() * 60000; //offset in milliseconds
var localISOTime = (new Date(Date.now() - tzoffset)).toISOString().slice(0, -1);
// => '2015-01-26T06:40:36.181'
