chosen.content: You can conditionally remove keys from a mapped type in TypeScript by producing the type never as a key. Here is an example mapped type that removes all number keys from a type:
  
  type ConditionallyRemoveKeys<Type> = {
      [Property in keyof Type as Exclude<Property, number>]: Type[Property]
  };
