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" : "neveropen"}); 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
