Created with StackBlitz ⚡️

Inversion of Control Container

This project represents an initial attempt at building an Inversion of Control Container. The majority of the code exists in src/ioc-container/container.ts I wrote a test suite to hold me to the mark as well as work as examples. You can see the tests in action by running npm run test:ui

Notes

TS

I chose to use Typescript for the project, though it does not always agree with what I am doing. I am using a Proxy to allow access to properties on an object that aren't actually there. As such it is hard to let TS know how to handle these things.
