The path.. about observ

[Raynos]

@gnimmelf observ is a single value. you listen to it and you get the entire new value when it changes.

@gnimmelf if you take a look at observ-struct and observ-array you can see they both support a feature called _diff

https://github.com/Raynos/observ-struct/blob/master/index.js#L39-L42
https://github.com/Raynos/observ-array/blob/master/splice.js#L45

In observ-struct and observ-array the _diff property is the most recent thing that caused a change, it is both the path and the value.

If you nest observ-struct and observ-array recursively the _diff will be a deeply nested diff object that will give you this information!

One trick I use in mercury a lot is

var state = window.state = mercury.struct({ 
  ...
})

Then in the browser dev tools I do window.state(function (x) { console.log('diff', x._diff) })

So I basically see exactly what changes when I click around :)

Indeed! Cool. Then it's settled: I'll swap out my own "masterpiece" with mercury.struct :-)
