JavaScript: Difference between toString() and toLocaleString() methods of Date

I am just checked in console of the Chrome for date and found the difference in the presentation format. Hope this could help.

var d = new Date();

console.log(d.toLocaleString()); //"04.09.2016, 15:42:44"
console.log(d.toString());       //"Sun Sep 04 2016 15:42:44 GMT+0300 (FLE Daylight Time)"

Converts a date to a string, using the operating system's locale's conventions.

toLocaleString behaves similarly to toString when converting a year that the operating system does not properly format.

https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date/toLocaleString

Basically, it formats the Date to how it would be formatted on the computer where the function is called, e.g. Month before Day in US, Day before Month in most of the rest of the world.

EDIT:

Because some others pointed out that the above reference isn't necessary reliable, how's this from the ECMAScript spec:

15.9.5.2 Date.prototype.toString ( )

This function returns a String value. The contents of the String are implementation->> dependent, but are intended to represent the Date in the current time zone in a convenient, human-readable form.

15.9.5.5 Date.prototype.toLocaleString ( )

This function returns a String value. The contents of the String are implementation->>dependent, but are intended to represent the Date in the current time zone in a convenient, human-readable form that corresponds to the conventions of the host environment‘s current locale.

Since you can hopefully assume that most implementations will reflect the specification, the difference is that toString() is just required to be readable, toLocaleString() should be readable in a format that the should match the users expectations based on their locale.
