jashkenas/backbone

Added the Backbone.localStorage adapter example, providing a client-side persistence solution that stores models in the browser's localStorage. This allows applications to maintain state locally without requiring a server, with the adapter handling create, read, update, and delete operations via the local storage API.

The todos example application has been added to the examples directory, providing a complete demo of a Backbone.js app with local storage persistence. The example includes the HTML structure, CSS styling, and JavaScript logic for managing a list of todos, including features like marking items as complete, editing, deleting, and filtering by status.

The debug information logic has been moved into a dedicated \modules/debug-info.js\ module, which now provides structured details about the runtime environment, including the versions of Backbone, Underscore/Lodash, and the JavaScript runtime (Deno, Node.js, or browser). An ESLint configuration file has also been added to the modules directory to support the new module's linting rules.

The internal implementation of the event system has been refactored to use arrays instead of linked-lists, resulting in a significant performance improvement (up to 20x faster in some cases). Additionally, the \Events\#off\ method now uses reverse iteration to avoid altering indices during event removal, and the \trigger\ method has been optimized to handle multiple events more efficiently.
