Exception: This is not a Date object when details===true

[lroal]

It throws an exception when calling a method on the date when details is true.

import onChange from 'on-change';

let proxy = onChange({ d: new Date() }, () => {}, { details: true});
proxy.d.getDate();
// throws

//                                        ^

Same issue here. @lroal did you manage to find a workaround? :)

[lroal]

No, I don't think I did.
I turned off detail

I think I used another tool to calculate the actual difference, fast-json-patch
And just used on-change to signal a change happened.

💥 wonderful idea: I actually only need to track dirty state. Way more efficient with object comparison. Thanks for the tips!
