is-false

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

$ 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.

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

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

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

When a property and it's inverse both exist, both must evaluate to the same result, or true is returned.

Examples

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
