Dot Prop Views

[Richienb]

Consider the following API:

import dotProp from 'dot-prop';

const object = {};
const view = dotProp(object);

view['foo.bar'] = 1;

console.log(object.foo.bar);
//=> 1

console.log(view['foo.bar']);
//=> 1

console.log('foo.bar' in view);
//=> true

delete view['foo.bar']

console.log('foo.bar' in view);
//=> false

Fully possible using Proxy

Seems like a cool experiment, but I'm finding it hard to think where I would want to use this in practice though. Proxy also comes with some performance and usability (does not work with private class fields, etc) downsides.

When would you use this and for what?

I was thinking something like using it alongside a flat database. Will leave this open for when someone reads about it here, then encounters a need for it in the wild.
