How can I do a deep comparison in store.$subscribe?

[ayochim]

One of the properties in my store is an object that gets replaced with another potentially equal object, but it's still triggering the callback. I'm not against using a third party equality check, but how do I access newValue and oldValue on mutation without typescript telling me it doesn't exist?

Edit: I just noticed the warning on mutation.events to not use it in production code. So now I'm not sure what to do.
