What is the best way to utilize the characteristics found in the properties of a different type?

Consider the following scenario:

type Individual = {
  name: string,
  age: number,
  nicknames: string[],
}

Now, I aim to generate a new type based on the types of the properties within the Individual type. The desired outcome is:

 type IndividualTypes = string|number|string[]

Is there a method to accomplish this task?

I have made attempts with variations of utilizing keyof and typeof, but I have not been successful.

Answer №1

To achieve that, the following code can be used:

type PersonTypes = Person[keyof Person]

If you are looking for a flexible generic solution that can be utilized with any type, you can use the code snippet below:

type ValueOf<T> = T[keyof T]
type PersonTypes = ValueOf<Person>
