The Lodash _.isZero() Method checks whether the given value is a Zero value or not and returns the corresponding boolean value.
Syntax:
_.isZero(value);
Parameters: This method accepts a single parameter as mentioned above and described below:
- value: Given value to be checked for Zero value.
Return Value: This method returns a Boolean value true if the given value is Zero, 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 the following command:
npm install lodash-contrib
Example 1:
// Defining underscore lodash variable var _ = require('lodash-contrib'); // Checking for _.isZero() method console.log("The Value is Zero : " + _.isZero(0)); console.log("The Value is Zero : " + _.isZero(10)); console.log("The Value is Zero : " + _.isZero(true)); |
Output:
The Value is Zero : true The Value is Zero : false The Value is Zero : false
Example 2:
// Defining underscore lodash variable var _ = require('lodash-contrib'); // Checking for _.isZero() method console.log("The Value is Zero : " + _.isZero(false)); console.log("The Value is Zero : " + _.isZero("0")); console.log("The Value is Zero : " + _.isZero({})); |
Output:
The Value is Zero : false The Value is Zero : false The Value is Zero : false
