Access nested object properties

[bartbutenaers]

Dear,

Thanks for sharing this very useful library!

I'm a bit confused about nested object properties.
I pass an object like this:

Which we try to validate using following expression:

msg.payload.open == true

From the readme page I understood this should be possible:

But I might have misinterpreted this??
And indeed while debugging, I see that this library checks whether the object has its own property "msg.payload.open" which is of course not the case:

Which means the nested property cannot be found :-(

However when I change the code to this:

    function prop(name, obj) {
        return name.split('.').reduce((obj, prop) => {
            return obj && obj[prop] ? obj[prop] : undefined;
        }, obj)
    }

    function safeGetter(obj) {
        return function get(name) {
            return name.split('.').reduce((obj, prop) => {
                return obj && obj[prop] ? obj[prop] : undefined;
            }, obj)
        }
    }

Then the nested property can be found without problems:

Thanks !!!
Bart
