Lodash _.isBoolean

Overview

The lodash _.isBoolean method is a utility function that is used to determine whether a given value is a boolean or not. It returns true if the value is a boolean and false if it is not.

This method works by checking if the type of the value is a boolean using the typeof operator. If the type is boolean, then it returns true. Otherwise, it returns false.

The _.isBoolean method is a part of the lodash library, which is a JavaScript utility library that simplifies programming with arrays, numbers, objects, strings, and more.

This method is commonly used in JavaScript programming to check the type of values returned from APIs, user input, or other sources of data. It helps to ensure that the code behaves consistently even when unexpected types of data are encountered.

Here is an example of how to use the _.isBoolean method:

const _ = require('lodash');

const value1 = true;
const value2 = 'false';

const result1 = _.isBoolean(value1); // true
const result2 = _.isBoolean(value2); // false
 
console.log(result1);
console.log(result2);

In the example above, the _.isBoolean method is used to check whether the value1 and value2 variables are booleans or not. The method returns true for value1 and false for value2.

In summary, the lodash _.isBoolean method is a powerful utility that simplifies programming in JavaScript by enabling developers to check whether a given value is a boolean or not. It helps to ensure that code behaves consistently even when unforeseen data types are encountered, resulting in more robust, maintainable, and error-free programs.
