Question

I have the following object:

var object = {
    "property1": "value1",
    "property2": "value2",
    "subobject": {
        "property1": "value1",
        "property2": "value2",
        "subobject": {
            "property1": "value1",
            "property2": "value2",
            "subobject": {...
            }
        }
    }
}

I am trying to set one of the nested subobject properties, but the nested level is dynamic.

How can I dynamically set one of these nested properties without doing something like this: object.subobject.subobject = { ... }?

Edit:
So to be more specific, I am trying to set one of the nested subobjects, but I won’t know which one each time.

Let’s use recursion!

function setNest(obj, level, val){
    if(level > 0){
        setNest(obj.subobject, level-1, val);
    }
    else{
        obj.subobject = val;
    }
}

Then call it like:

setNest(object, 2, {a: 12});
