Running moment.js, 2.2.1
moment(2010-10-319, [YYYY-MM-DD]).isValid()
... returns true, and the moment object would be set to 31 October 2010. The parser seems to strip extraneous characters of any sort:
moment(2010-10-31a, [YYYY-MM-DD]).isValid(); // true
Curiouser, if you add additional format choices, then the stripping becomes limited to only one character! (Shouldn't the format strings tests be ORed?)
moment(2010-10-319, [MM/DD/YYYY, MM-DD-YYYY, YYYY-MM-DD]).isValid(); // true
moment(2010-10-3199, [MM/DD/YYYY, MM-DD-YYYY, YYYY-MM-DD]).isValid(); // false (!!!)
Is this behaviour by design? I'm not getting why.
EDIT: A commenter found another case where extra characters beyond one are, indeed, stripped:
moment(2010-10-319qr, [MM/DD/YYYY, MM-DD-YYYY, YYYY-MM-DD]).isValid(); // true (!)
Here is is in action: http://jsfiddle.net/grahampcharles/r42jg/6/ (updated with new case)
