The Lodash _.isNegative() method checks whether the given value is a Negative value or not and returns the corresponding boolean value.
Syntax:
_.isNegative( value );
Parameters: This method takes single parameter as mentioned above and described below:
- value: Given value to be checked for Negative value.
Return Value: This method returns a Boolean value true if the given value is Negative, 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
var _ = require( 'lodash-contrib' );
console.log( "The Value is Negative : " + _.isNegative(-500));
console.log( "The Value is Negative : " + _.isNegative(500));
console.log( "The Value is Negative : " + _.isNegative( 'G' ));
|
Output:
The Value is Negative : true
The Value is Negative : false
The Value is Negative : false
Example 2:

var _ = require( 'lodash-contrib' );
console.log( "The Value is Negative : " + _.isNegative(-10.5));
console.log( "The Value is Negative : " + _.isNegative(10.5));
console.log( "The Value is Negative : " + _.isNegative({}));
