 The advantage of loading a bean using just the simple class name (e.g. `data-sly-use.page="PageBean"`) is that an inheriting component can overlay the `PageBean.java` file and provide a different logic. In this case the package name of the `PageBean` class will automatically be derived from the calling script's parent path (e.g. `apps.my_project.components.page`) - the bean doesn't even have to specify it. However, keep in mind that loading a bean this way is slower than providing the fully qualified class name, since the provider has to check if there is a backing resource. At the same time, loading an object using its fully qualified class name will not allow overriding it by inheriting components.

 With the exception of the `console` and `use` objects, all the other global objects implemented by the JavaScript Use Provider are present in order to support the asynchronous Resource-API implemented by `org.apache.sling.scripting.sightly.js.provider`. However, this was deprecated starting with version 1.0.8 - see [SLING-4964](https://issues.apache.org/jira/browse/SLING-4964).
