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.
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
