## DO NOT USE

This project has never been seriously maintained, and you should be using [eslint-plugin-fp](https://github.com/jfmengels/eslint-plugin-fp) directly instead.

# eslint-config-cleanjs

This is an ESLint configuration which aims to restrict you to a subset

of JavaScript which would be as close to an idealised pure functional

language as possible. The idea is to see if it's possible to banish

all the Bad Parts (well, except for the single numeric type being IEEE

754 floating point) and leave a language without the design flaws

which have plagued JS from the start, and which aren't easy to design

out of the language without becoming a subset of itself.

Please note that this rule set is meant for use only with ES6 or

higher (and the ES7 object rest spread proposal helps a lot).

Highlights:

* no `this` and no classes

* no `null` and `undefined` (implying that all functions must `return`)

* no mutation of any kind

* no variable reassignment

* no statements, only expressions (including no `if`)

* no CommonJS or AMD, only ES6 modules

This is all based on three ESLint plugins, which you'll have to

install to use these presets:

* [eslint-plugin-better](https://github.com/idmitriev/eslint-plugin-better)

* [eslint-plugin-fp](https://github.com/jfmengels/eslint-plugin-fp)

* [eslint-plugin-import](https://github.com/benmosher/eslint-plugin-import)

## Usage

Just install this package somewhere your eslint can find it (`npm

install -g eslint-config-cleanjs` if your eslint is installed with

`-g` too), along with the three above mentioned plugins (`npm install -g

eslint-plugin-better eslint-plugin-fp eslint-plugin-import`), and put

this in your `.eslintrc` or wherever you keep your project's eslint

config:

```

{

  "extends": "cleanjs"

}

```
