This example shows a JavaScript implementation of a dependency-injection system called `librarySystem`, which manages named libraries and their dependencies. The code defines a function that stores library definitions in a `libraryStorage` object, allowing callbacks to receive resolved dependency libraries as arguments. It demonstrates how to register libraries with empty dependency arrays and how to retrieve them by name, as seen in the commented examples. The system uses the `window.myLibs` assignment to expose the `librarySystem` function globally.
