Javascript: Get deep value from object by passing path to it as string [duplicate]

by

This works correctly:

var deep_value = function(obj, path){
    for (var i=0, path=path.split('.'), len=path.length; i<len; i++){
        obj = obj[path[i]];
    };
    return obj;
};

Here is the proof / demo: jsfiddle.net/tadeck/5Pt2q/13/

EDIT: I have removed redundant variables, shortened the code.
