How to make an object into text in js

Question

Here is a js object that represents the file system in the command line os project I'm working on:

var obj = {
        "1": {
            "hi": "hi"
        }, 
        "2": {
            "bye": "bye"
         }
    };
var currentDir = obj["1"]["hi"];
console.log(currentDir);

When I run this, I get

"hi"

How do I get this to appear as

/1/hi/

I need to get the "file path" of the currently select object.

Your code logs "hi" when I run it, not "[object Object]". — gen_Eric

@Chase Welcome to StackOverflow. It's not very clear what you're trying to do, because it doesn't seem like you have an understanding of the language constructs that you're using. I recommend doing some reading about javascript objects and arrays, and the accessors for each. When you have a better understanding, come back and revise your question. — xdumaine

@Chase: That is fundamentally impossible. The same string can be referenced by multiple objects. You need to re-think your design. — SLaks

@Chase, as you're entering "1" and "hi" manually, why can't you just do "1" + "/" + "hi" + "/"? — Paul S.

Don't you already know the path when you address the object? do something like console.log(firstIndex + '/' + secondIndex + '/ + obj[firstIndex][secondIndex]); — Yotam Omer

Make some kind of lookup function

var lookup = (function (o) {
    return function lookup() {
        var i, e = o, s = '';
        for (i = 0; i < arguments.length; ++i) {
            s += '/' + arguments[i];
            if (!e.hasOwnProperty(arguments[i]))
                throw "PathNotFoundError: " + s;
            e = e[arguments[i]];
        }
        return {path: s, value: e};
    }
}(obj));

And using it

console.log(lookup('1', 'hi').path); // "/1/hi"

Your code returns "hi" So does var currentDir = obj[1].hi;

I need to get the path of objects to the current object

You already know the path when you access your object. do something like this:

console.log(firstIndex + '/' + secondIndex + '/ + obj[firstIndex][secondIndex]);

you can use this in for loops, each loops while etc.. or by direct access like your example.
