How to affect an object with multiple keys for the same value

Question

I have some rules lookups that are based on state.. I am trying to think of a way to make accessing these easy without setting up some sort of intermediate step.

I'm imagining something like:

rules = {
  ['AK','FL','NY']: {a: 278},
  ['CA','LA','TX']: {a: 422}
}
console.log(rules['AK']); //278
console.log(rules['TX']); //422

I know that's not possible.. but wondering what the simplest way to achieve something like that would be

Answer 1

Take a page from MySQL's foreign key :

var states = {
   'AK' : 1,
   'FL' : 1,
   'NY' : 1,
   'CA' : 2,
   'LA' : 2,
   'TX' : 2
}

var rules = {
    1 : 278,
    2 : 422
}

Then you can reference the rules like so :

console.log(rules[states['AK']]);

Answer 2

Affect Keys with same rule :

var rule1 = {a : 278}; 
var rule2 = {a : 422}; 

var rules = {
     'AK' : rule1, 
     'FL' : rule1, 
     'NY' : rule1, 
     'CA' : rule2, 
     'TX' : rule2
}; 

console.log(rules['AK']);   // {a:278}
console.log(rules['AK'].a); // 278
