deletedDiff returns undefined values that are not JSON valid

[boshka]

Could there be an option that would result in deletedDiff returning other values, such as null instead of undefined?

Hey @boshka this sounds similar to this issue #10 what you can do is supply a replacer function to JSON.stringify to convert the undefined values to null or anything you like. There is an example of this in action in #10

Let me know if that solves your problem

Hi Matt,
sorry, haven't noticed that solution. Thank you, that works!
