javascript Date() object returns valid but not new Date()

Question

var d = Date("12:00 AM") returns as a date just fine, however when trying to create an instance of it new Date("12:00 AM") it returns 'Invalid date'.

I found a solution here, using moment.js, which works fine, but I would like know why getting 'Invalid Date' when using 'new Date()'

Thanks

`Date()` (without `new`) does not take a parameter and just yields the current date as a string — Bergi, Sep 21 '14 at 17:54
`12:00 AM` is only a time, not a date, and therefore too less information to make a valid datetime. What output would you expect? — Bergi, Sep 21 '14 at 17:55

From MDN:

Note: Note that JavaScript Date objects can only be instantiated by calling JavaScript Date as a constructor: calling it as a regular function (i.e. without the new operator) will return a string rather than a Date object; unlike other JavaScript object types, JavaScript Date objects have no literal syntax.

...

Invoking JavaScript Date as a function (i.e., without the new operator) will return a string representing the current date and time.

The first version of your call ignores the argument (and doesn't actually produce a Date).
