Why would anyone build with this?

REASON 1

Automatically wire dependencies between classes instead of manually passing objects around

REASON 2

Reduce boilerplate in a large TypeScript project where many components reference each other

REASON 3

Bring Angular-style dependency injection to a non-Angular TypeScript codebase

REASON 4

Make code easier to test and refactor by decoupling how components get their dependencies
