Lodash _.truthy() Method

The Lodash _.truthy() method checks whether the given value is truthy or not and returns the corresponding boolean value. A truthy value is one that coerces to true in a boolean context.

Syntax:

_.truthy( value );

Parameters: This method accepts single parameter as mentioned above and described below:

• value: Given value to be checked for truthy value.

Return Value: This method returns a Boolean value true if the given value is truthy, else false.

Note: This will not work in normal JavaScript because it requires the lodash.js contrib library to be installed. Lodash.js contrib library can be installed using npm install lodash-contrib.

Example 1:

Javascript

// Defining underscore lodash variable
var _ = require('lodash-contrib');

var bool = _.truthy(true);
console.log("Given Value is True or not : ", bool);

var bool = _.truthy(false);
console.log("Given Value is True or not : ", bool);

Output:

Given Value is True or not : true
Given Value is True or not : false

Example 2:

Javascript

// Defining underscore lodash variable
var _ = require('lodash-contrib');

var bool = _.truthy(10);
console.log("Given Value is True or not : ", bool);

var bool = _.truthy([10, 30, 50]);
console.log("Given Value is True or not : ", bool);

var bool = _.truthy({"G" : "GeeksforGeeks"});
console.log("Given Value is True or not : ", bool);

Output:

Given Value is True or not : true
Given Value is True or not : true
Given Value is True or not : true
