compare only keys

[jmls]

is it possible to compare 2 json objects and only compare the key names, rather than the values ?

for example

var a = { foo: 'bar', baz:true}
var b = { foo: 'boo', bingo:false}

if I compare b with a, I would like to get that baz has been added, bingo removed and ignore foo

in this event, I want b to end up being

{ foo: 'boo', baz:true }

Thanks for the question, @jmls. I've opened #23 to track the ability to support this.
