first(type, …)

last(type, …)

Returns the last argument of the specified type

da.last('object', 1, null, 'a', {foo: 'bar'}, {}) // {foo: 'bar'}
da.last.boolean(1, 2, true, false) // false

not(type, …)

Returns the first type that does not match the specified type

da.not('number', 1, 2, 'a', 3) // 'a'
da.not.array([1], [2, 3], undefined, [4]) // undefined
