Installation
$ npm install boolean
Quick start
First you need to add a reference to boolean in your application:
const { boolean } = require('boolean');
If you use TypeScript, use the following code instead:
import { boolean } from 'boolean';
To verify a value for its boolean value, call the boolean function and provide the value in question as parameter.
console.log(boolean('true')); // => true
The boolean function considers the following values to be equivalent to true:
true(boolean)'true'(string)'TRUE'(string)'t'(string)'T'(string)'yes'(string)'YES'(string)'y'(string)'Y'(string)'on'(string)'ON'(string)'1'(string)1(number)
Please note that if you provide a string, it will be trimmed.
All other values, including undefined and null are considered to be false.
