## What it is
A curated guide listing native JavaScript and modern library (date-fns, Day.js, Luxon) replacements for Moment.js functions, plus an accompanying ESLint plugin. It helps developers reduce bundle size by migrating away from Moment.js.

## Use cases
- replace moment.js with native date functions
- reduce javascript bundle size from date library
- migrate from momentjs to date-fns
- find momentjs alternative for tree-shaking
- lint codebase to flag momentjs usage
- learn date formatting without a library

## When to choose
- you use only a few simple date functions from moment.js
- bundle size and performance matter for your web app
- you want a migration reference to date-fns, Day.js, or Luxon

## When to avoid
- you need moment.js's full timezone and locale support
- you want a runnable date library rather than a guide
