Answer 1

Your date string (whatever it is "31-08-2016") isn't in a format recognized by the Date constructor. So you ended up with a Date whose underlying time value is NaN, which is shown as "Invalid Date" when you ask for the string version. Gratuitous example:

console.log(new Date("foobar").toString());
