Why use @Inject in nestjs?

Question

Node.js

There is a module in the service of which I want to use another module.
What will be the difference between records?

@Inject('Enum')
    private readonly EnumService: Enum

and
private readonly EnumService: Enum

if in both cases it is necessary to prescribe module imports ?

If your class doesn't extend another provider, you should always prefer using constructor-based injection.
