## Description

InversifyJS is an inversion of control framework and dependency injection library for TypeScript. It provides a centralized container to manage object lifecycles and automate the instantiation of classes and their dependencies.

The library decouples software components by mapping unique identifiers to concrete implementations. This architecture separates object creation from business logic and allows for the replacement of real service implementations with mock objects during unit testing.

The framework utilizes TypeScript decorators to provide metadata-driven injection and recursive dependency resolution. It manages the application object graph through container-based service location and lazy-loaded instance management.
