Function inject

Given a set of modules, the inject function returns a lazily evaluated injector that injects dependencies into the requested service when it is requested the first time. Subsequent requests will return the same service.

In the case of cyclic dependencies, an Error will be thrown. This can be fixed by injecting a provider () => T instead of a T.

Please note that the arguments may be objects or arrays. However, the result will be an object. Using it with for..of will have no effect.
