Is this value a JS Boolean? This module works cross-realm/iframe, and despite ES6 @@toStringTag.
Package description
The is-boolean-object npm package is a utility that allows you to determine if a given value is a boolean object. This can be particularly useful in scenarios where you need to validate or enforce data types in your JavaScript code.
Check if a value is a boolean object
This feature allows you to check if a given value is a boolean object. The code sample demonstrates how to use the is-boolean-object package to differentiate between primitive boolean values and boolean objects.
const isBooleanObject = require('is-boolean-object');
console.log(isBooleanObject(true)); // false
console.log(isBooleanObject(false)); // false
console.log(isBooleanObject(new Boolean(true))); // true
console.log(isBooleanObject(new Boolean(false))); // trueThe is-boolean package is a utility that checks if a value is a boolean primitive. Unlike is-boolean-object, it does not check for boolean objects created with the Boolean constructor.
The lodash.isboolean package is part of the Lodash library and checks if a value is a boolean primitive. It is similar to is-boolean but is part of a larger utility library, offering more functionality beyond just type checking.
The is-primitive package checks if a value is a primitive type, including boolean primitives. It does not specifically check for boolean objects, making it broader in scope compared to is-boolean-object.
