is-false

0.1.1 • Public • Published

is-false NPM version

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

Install

Install with npm

$ 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

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 ;)

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
