How to make an object's dynamic key based on the values ​​of another object?

Question

typescript

Good day.
There is an object that is a map of aliases and possible values.

const TYPES = {
   TYPE: 'type',
   ANOTHER_TYPE: 'anotherType',
}

It is necessary to describe an object that can store functions by keys, which are the values ​​of the TYPES object. That is, this object looks like this:

const object = {
   type: () => {},
   anotherType: () => {},
}

In this case, the task is complicated by the fact that keyof will return the union of keys, and valueof, unfortunately, was not delivered to TS. Having a second object (Object.values(TYPES)) is such an option, because in this case keyof will litter possible keys with various length and other properties and methods built into the Array prototype.
How to solve the problem in the most elegant way?

Answer 1

interface Types {
  TYPE: 'type';
  ANOTHER_TYPE: 'anotherType';
}

type SomeType = {
  [P in Types[keyof Types]]: () => void;
};

const object: SomeType = {
  type: () => {}, 
  anotherType: () => {}
}
