## What it is
A curated reference list of JavaScript methods that natively replace Lodash/Underscore utilities, plus a companion ESLint plugin that flags replaceable Lodash/Underscore calls. It helps developers reduce dependencies by using built-in ES5/ES6+ methods.

## Use cases
- find native JavaScript alternatives to Lodash methods
- remove Lodash dependency from my project
- lint code to avoid unnecessary Lodash usage
- check if Array.prototype covers my utility needs
- learn modern ES6 array and object methods
- reduce bundle size by dropping utility libraries

## When to choose
- targeting modern browsers or Node.js with ES5/ES6+ support
- you want fewer dependencies and smaller bundles
- you need a quick reference for native equivalents of utility functions
- you want automated linting to enforce native method usage

## When to avoid
- supporting legacy JavaScript engines without ES5 shims
- you rely on Lodash's richer options like deep cloning, chaining, or debouncing
- you need a 1:1 drop-in replacement for all Lodash features
