This addon provides a polyfill for RFC 580 "Destroyables", which adds an API for registering destroyables and destructors with Ember's built-in destruction hierarchy. It allows developers to create and manage destroyables, associate them with parent destroyables, and automatically clean up resources when objects are destroyed. The polyfill is designed for Ember.js applications using versions 3.4 and above (inert for 3.22.0-alpha.1 and above) and helps manage cleanup tasks like timers, event listeners, and other resources that need to be disposed of when components are destroyed.
