Description
Given
console.log($.map([ 1, undefined, , 2, null, 3 ], function (e, i) { return e; }));
results in
[ 1, 2, 3 ]
where I'd expect
[ 1, undefined, undefined, 2, 3 ]
Underlying problem is that we compare using
value != nullinstead of
value !== null
I am sure there is code depending on
undefinedto remove the element by now, so I don't think we want to change the behavior. Instead I think we should document the current behavior.
