## Description

core-decorators is a JavaScript class decorator library and framework utility for extending class functionality. It provides a collection of tools for implementing class behavior mixins, automating method binding to avoid manual constructor configuration, and verifying that subclass methods correctly override parent methods.

The library includes a code deprecation toolkit for flagging obsolete methods with console warnings and a function execution profiler for measuring performance and duration. It further enables the modification of class and method behavior through a system of custom decorators and shared logic injection.

Additional capabilities cover object property control, including the enforcement of read-only properties and the restriction of property visibility. The toolkit also provides performance primitives such as result caching and deferred property initialization to delay execution until first access.
