I have a class that has a static dictionary that maps ids to names

class Foo {
  static idToName = {
    2: "John",
    8: "Peter"
  }
}

Now, I also need to be able to get the id given a name, so I need the inverse dictionary

class Foo {
  static idToName = {
    2: "John",
    8: "Peter"
  }
 
  static nameToId = {
    "John": 2,
    "Peter": 8
  }
}

Can I avoid hardcoding this inverse dictionary and generate it with code?

At the end I need to be able to do

Foo.idToName(2)  -> "John"
Foo.nameToId("John")  -> 2

Is that possible?
