I find it harder to determine what's actually going on. But maybe it just
takes a little time getting used to. Clearly not the way to go for apps
where speed is important, but I suppose it works otherwise. Also, there's no
way to detect errors (maybe you require those vars to be set) this way.
If you want these kind of key lookup storage structures, why not create a
function to do it for you? Something like...
var Config = {bridge:{meta:{name:'peter',age:29}}};
function get(key){
var arr = key.split('.'); // ['bridge','meta','name']
var result = Config;
while (arr.length && (result = result[arr.shift()]))
console.log(result);
return result;
};
var name = get('bridge.meta.name'); // peter
var age = get('bridge.meta.age'); // 29
var occupation = get('bridge.meta.children'); // undefined
The build up of such structure would be similar. I'll leave that up to you
:)
Similarly, to cover error checking, you could do a hasPath in a similar
fashion. This allows you to abstract that "does it exist" logic away and
leave your business logic in plain view.
Just my two cents :)
