## What it is
Memoizee is a comprehensive memoization library for JavaScript that caches function results to avoid repeated computation. It supports any argument types and lengths, promise-returning and async functions, LRU size limits, cache expiration, WeakMap-based garbage-collection-friendly modes, and profiling statistics.

## Use cases
- memoize expensive function calls in JavaScript
- cache results of async functions and promises
- limit cache size with LRU eviction
- expire cached values after a timeout
- memoize object methods including this binding
- avoid recomputing results for repeated identical arguments

## When to avoid
- you need a distributed or persistent cache across processes or servers
- you only need simple key-value caching rather than function memoization
- your project is TypeScript-first and prefers a natively typed memoization library

## Facets
- artifact type: library
- maturity: stable
- function: caching, concurrency
- domain: developer-tools, performance, web-development
- platform: browser
- tags: memoization, lru-cache, async-cache, weakmap, cache-expiration, nodejs, javascript
