## What it is
fast-memoize is a JavaScript memoization library that caches function results to speed up repeated calls with the same arguments, supporting functions with N arguments. It aims to be the fastest memoization library available and supports custom cache and serializer implementations.

## Use cases
- memoize expensive function calls in javascript
- cache function results by arguments
- speed up repeated computations in node
- memoization library supporting multiple arguments
- plug in a custom cache or serializer for memoization

## When to choose
- you need maximum memoization performance in JavaScript
- you need memoization for functions with multiple arguments
- you want to swap in a custom cache or serializer

## When to avoid
- you need to memoize functions with non-deterministic or object-heavy arguments without a serializer
- you need a maintained library with active development
- you need async function memoization

## Facets
- artifact type: library
- maturity: maintenance
- function: caching, serialization
- domain: developer-tools, performance, web-development
- platform: browser
- tags: memoization, function-caching, performance-optimization, nodejs, javascript
