## What it is
A tiny JavaScript library providing three ES7 decorators: @bind, @debounce, and @memoize. It is designed to simplify common class method patterns, particularly in Preact class components.

## Use cases
- bind class methods to a fixed this value
- debounce frequently called methods
- memoize expensive function results by argument
- simplify React or Preact class component handlers
- avoid writing custom decorators in a codebase

## When to choose
- you use Babel or TypeScript with experimental decorators and want standard, recognizable method decorators
- you need a tiny, dependency-free bind/debounce/memoize utility for class-based components

## When to avoid
- you write functional components or modern code without decorator support
- you need advanced memoization with multiple-argument cache keys or LRU eviction
- you need actively maintained libraries with recent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: caching, middleware
- domain: developer-tools, web-development, frontend
- platform: browser
- tags: decorators, debounce, memoization, bind, es7, preact, nodejs, javascript
