Returns `true` if the value of an object's property is strictly true, or it's inverse is false.

is-true

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

Install

Install with npm

$ npm i is-true --save

Usage

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

var isTrue = require('is-true');

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

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

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

Examples

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

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

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