Best way to write an object which selects propery based on 2 criteria in JS

Question

I have a requirement where it is necessary to have 2 levels of nesting in an object with state and type something like below

templates = {
   type1: {
              state1: [];
          }
   type2: {
              state2: [];
          }
};

However in one of the cases, I wont be having type but I need to select just based on state in this case. How to achieve this?

Your code is syntactically invalid, due to the semi-colons. You say *I need to select*--select what? — , Sep 09 '16 at 09:51

You could always add another item to your object wich defines the way it should be accessed.

template = {
    // and then either

    accessType : "type",
    type1: {
        state1: [];    
    },
    type2:{
        state2: [];
    }

    // or
    accessType : "state",
    state1: {

    },
    state2: {
    }
}

Based on the accessType you can decide how you want to access the object.
