Object with index as keys should not equal array

[a-b-r-o-w-n]

expect({ 0: 'hello', 1: 'world' }).toEqual([ 'hello', 'world' ]);

I don't think this should pass, but it does. Is there something I am missing, or is this not intended?

JavaScript arrays are actually objects (with special semantics). I see no reason why that test shouldn't pass.
