## Description

Aspects is an aspect-oriented programming library and method hooking framework designed for intercepting and modifying JavaScript function behavior without altering the original source code. It serves as a runtime logic injector that allows for the addition and removal of executable code wrappers from active functions.

The library enables the injection of custom logic before or after methods to change application behavior at runtime. It further provides the ability to intercept method calls to capture or override return values before they reach the caller.

The framework manages these interceptions through a dynamic proxy wrapper and uses token-based tracking to deregister specific logic layers and restore original method behavior.
