Many years since the original post. Now there is a great library called 'object-path'. https://github.com/mariocasciaro/object-path

Available on NPM and BOWER https://www.npmjs.com/package/object-path

It's as easy as:

objectPath.get(obj, "a.c.1");  //returns "f"
objectPath.set(obj, "a.j.0.f", "m");

And works for deeply nested properties and arrays.
