I want it on the other side (on the function return) so that it's consistently displayed in type hints and intellisense so I don't have to navigate the code backwards 3-4 layers to find the root type (do you see what I'm saying?) function checkDogs(dogs: Dog[]) : DogBreedAndSize[] { return dogs.map(d => /* ... */) } ^^^ That's where it's important to not skip the type def because then I can see the root type in the editor hints and I don't need to dig into the call stack (I know the end result is the same whether it's on the assignment side or the declaration side, but it feels like ensuring it's always on the declaration side is where the value is)
