## What it is
Just is a collection of zero-dependency JavaScript utility modules, each published as its own tiny npm package that does one thing (e.g. just-clone, just-diff, just-extend). It ships ES and CJS builds plus TypeScript definitions, making it ideal for size-sensitive apps like PWAs.

## Use cases
- deep clone objects without pulling in lodash
- diff and patch JavaScript objects
- merge, extend, pick, and omit from objects
- reduce bundle size by replacing bulky utility libraries
- add small typed utilities to a TypeScript project
- build a progressive web app with minimal bytes

## When to choose
- you need a handful of small utilities and care about bundle size
- you want dependency-free npm packages with ESM/CJS and TypeScript support
- you're targeting older browsers or Node 6+ environments

## When to avoid
- you want one comprehensive utility library with batteries included
- you need heavily optimized or battle-tested performance-critical utilities
- your team prefers a single dependency over many micro-packages

## Facets
- artifact type: library
- maturity: active
- function: developer-tools
- domain: developer-tools, web-development
- platform: browser, cross-platform
- tags: utility-library, zero-dependency, npm-packages, typescript-definitions, pwa, tree-shakable, javascript, nodejs
