## What it is
An ESLint shareable config that restricts JavaScript to a pure functional subset by banning this, classes, null, mutation, reassignment, and statements. It is explicitly unmaintained and its README directs users to eslint-plugin-fp instead.

## Use cases
- enforce pure functional style in JavaScript
- ban mutation and null in a JS codebase
- write JavaScript without this and classes
- restrict JS to expressions only with ESLint
- experiment with functional-only JavaScript subset

## When to choose
- you want a ready-made strict functional ESLint preset for an ES6+ experiment project

## When to avoid
- you need maintained tooling - use eslint-plugin-fp directly
- your codebase uses classes, mutation, or CommonJS
- you need production-grade linting with support

## Facets

- maturity: abandoned
- function: linter, code-review
- domain: developer-tools, programming-languages
- platform: -
