import { core } from 'my-library'; const registry = core.registry.create(); registry.pipeline.add({ process(item) { return item.toUpperCase(); } }); registry.register('hello', 'world'); const result = registry.get('hello'); // "WORLD"In this example, the `Pipeline` added to the registry simply transforms the input item by converting it to uppercase. When the registry is queried for the value of the `hello` key, the resulting value is `"WORLD"`. It's difficult to determine the package library without additional context, but based on the naming convention and usage of the `core.registry` module, it's likely that this code is part of a larger library used for creating modular, extensible applications.
