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)

In addition to the primitive types mentioned above, boolean also supports their object wrappers Boolean, String, and Number.

Please note that if you provide a string or String object, it will be trimmed.

All other values, including undefined and null are considered to be false.
