Examples
Invalid cases
Unrecognizable strings or dates containing illegal element values in ISO formatted
strings usually return NaN
. However, depending on the implementation,
non–conforming ISO format strings, may also throw RangeError: invalid date
,
like the following cases in Firefox:
js
new Date("foo-bar 2014");
new Date("2014-25-23").toISOString();
new Date("foo-bar 2014").toString();
This, however, returns NaN
in Firefox:
js
Date.parse("foo-bar 2014"); // NaN
For more details, see the Date.parse()
documentation.
Valid cases
js
new Date("05 October 2011 14:48 UTC");
new Date(1317826080); // Unix Timestamp for 05 October 2011 14:48:00 UTC
