What is the best way to create a generic variable and function that utilize the same type?

I am looking for a structure similar to

interface propType {
  value: T
  action: (value: T) => void
}

The variable T can be any type, but it must be consistent for both value and action. Using any is not suitable as it could lead to a mismatch in types.

Answer №1

You were incredibly close:

type customType<T> {
  data: T
  process: (data: T) => void
}
