No. I know what DI is. The debate is similar to imperative vs. OOP. But this is not exactly what I am referring to. Literally look at the second example, it's DI over and over and over again.

I am referring to DI 100%. Function composition works better and is a replacement for DI. You're the one that isn't getting it.

Either way, imperative programming and OOP are orthogonal concepts. There never really was an argument about imperative vs. OOP.

Additionally function composition is an FP concept. I'm not promoting FP over OOP here... far from it, I am simply saying that specifically for DI, you can borrow a pattern from FP and use it in place of DI because function composition is a much better pattern.
