A small, self-contained class that manages cleanup functions for a component. It provides onDestroy() to register teardown logic and destroy() to execute all. This pattern prevents memory leaks and is reusable in any JavaScript project needing lifecycle-aware components.

A single-function utility that creates DOM elements with attributes (including dataset, className, event listeners) and appends child nodes or text. It simplifies DOM construction, reduces boilerplate, and is framework-agnostic. Could be extracted into any project that needs concise element creation.

Transforms an indexed JSON format (services array + host-to-indices mapping) into a flat, host-to-service-status object. Useful for any application that receives compact indexed data and needs a denormalized view for rendering tables. It is stateless and pure.

A bash script that converts checkmark/cross JSON data into a compact indexed format for better performance. It factors out common service names, maps to indices, and removes redundancy. This script can be reused on any similar dataset (e.g., feature matrices, compatibility lists) to reduce file size and improve load times.
