Answer 1

When you have lodash in your application anyway, you can simply utilize lodash's isEqual() function, which does a deep comparison and perfectly matches the signature of distinctUntilChanged():

.distinctUntilChanged(isEqual),

Or if you have _ available (which is not recommended anymore these days):

.distinctUntilChanged(_.isEqual),
