Why is the joke with Java always factories? Factories are really super useful in a dependency injection context.

I've been working primarily in Go for the past five years, including some extremely complex projects, and I have never once wished I had dependency injection. It has been wonderful. I have used dependency injection - previously I worked on a C# project for years, and that used DI - but I adore Go's simplicity and I never want to use anything else (except for JS for UI, via Electron or Wails for desktop).

Edit: If we're talking about dependency injection in the general sense (separation of concerns, modularization, loose coupling), then yeah I agree that's kind of critical to writing good, maintainable software. When I hear "dependency injection" I think of frameworks such as Unity, and that is what I was specifically talking about - I am very happy with the fact that I have felt zero need to use any framework like that over the last five years.

Do you write unit tests with objects mocked via interfaces? Or polymorphism via interfaces? Those are the main reasons to use DI.

I guess I have to start calling function invocation with generic parameters, fancy names (like "dependency injection" ^^)

As I read somewhere:

Dependency Injection is a 25-dollar term for a 5-cent concept.

Yea that works too.
