Ensuring Two Members in a Class are of Matching Types

I need to verify that two members of my class are of the same type, but I do not know what type they are. Any suggestions?

I have attempted the following approach, but it did not work:

interface Foo {
  bar: Foo["baz"];
  baz: Foo["bar"];
}

Answer №1

If you're looking to make your code more flexible, it might be worth considering the use of generics.

Take a look at this example:

interface Bar<TElement> {
  foo: TElement;
  foobar: TElement;
}

In this scenario, TElement acts as a placeholder for a specific type. Instead of using just Bar, you can specify Bar<string> if both foo and foobar are expected to be strings. Alternatively, you can go with Bar<unknown> to allow for any type.
