How to delete nested object attribute [duplicate]

Question

I have a object like this.

var Obj = {
    obj1 : {
        val : 1,
        id : 1
    }
    obj2 : {
        val : 2,
        id :2
    }
    obj3 : {
        val : 3,
        id :3
    }
}

I want to delete obj1, can anybody suggest how to achieve this.
