## README

# is-false [![NPM version](https://badge.fury.io/js/is-false.svg)](http://badge.fury.io/js/is-false)

> Returns false if the value of a property is either strictly false, or it's inverse is strictly true.

## Install

Install with [npm](https://www.npmjs.com/)

```sh
$ npm i is-false --save
```

## Usage

Returns true if a property is strictly `false` or its inverse is strictly `true`. The inverse of `a` is `noa`, the inverse of `b` is `nob`, and so on.

**Examples**

```js
var isFalse = require('is-false');

isFalse({a: false}, 'a');
//=> true

isFalse({noa: true}, 'a');
//=> true
```

## Conflicts

When both a property and its inverse exist, `true` is always returned unless both values evaluate to `true` (remember that this repo is named `isFalse` ;)

```js
isFalse({noa: true, a: false}, 'a');
//=> true

isFalse({noa: true, a: true}, 'a');
//=> true

isFalse({noa: false, a: false}, 'a');
//=> true

isFalse({noa: false, a: true}, 'a');
//=> false
```
