Dependencies

Hi,

I've only skimmed a few chapters, but this is really good stuff!

I'm surprised there's no mention of dependency injection or IOC?

This is one of my favorite JS patterns:

I also have different versions of "mostly types" lightweight DI containers in JS - literally just a few lines that work both for objects and functions:

Maybe this inspires something for your book? I dunno. These are some of my favorite JS patterns for sure.
