## What it is
A JavaScript library that generates hashes from arbitrary JavaScript objects, working in both Node.js and the browser. It supports hashing algorithms like SHA1 and MD5 and handles nested object structures deterministically.

## Use cases
- generate a hash from a javascript object
- compare two objects for equality by hashing them
- create cache keys from object contents
- detect changes in object state
- hash objects in the browser and node consistently

## When to choose
- you need deterministic hashes of JS object structures
- you want a small dependency-free hashing utility usable in node and browser

## When to avoid
- you need cryptographic security guarantees against collisions
- you need to hash non-serializable values like functions with side effects

## Facets
- artifact type: library
- maturity: stable
- function: serialization, cryptography
- domain: developer-tools, web-development
- platform: browser
- tags: object-hash, hashing, sha1, md5, javascript, algorithms, nodejs
