Underscore.js _.neq() Method
The _.neq() method checks whether each argument is not equal to the previous argument, using loose inequality (!=). Hence, returning a boolean correspondingly.
Syntax:
_.neq( val1, val2, ..., valn );
Parameters: This method takes n values to operate on them.
Return Value: This method returns a boolean.
Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed.
underscore.js contrib library can be installed using npm install underscore-contrib –save.
Example 1: In this example, we will see the use of the _.neq() method.
javascript
// Defining underscore contrib variable const _ = require( 'underscore-contrib' ); let neq = _.neq(3, 1); console.log( "Each arguments are not equal to previous one :" , neq); |
Output:
Each arguments are not equal to previous one : true
Example 2: In this example, we will see the use of the _.neq() method.
javascript
// Defining underscore contrib variable const _ = require( 'underscore-contrib' ); let neq = _.neq(4, 4); console.log( "Each arguments are not equal to previous one :" , neq); |
Output:
Each arguments are not equal to previous one : false
Example 3: In this example, we will see the use of the _.neq() method.
javascript
// Defining underscore contrib variable const _ = require( 'underscore-contrib' ); let neq = _.neq(4, 2, 1); console.log( "Each arguments are not equal to previous one :" , neq); |
Output:
Each arguments are not equal to previous one : true
Example 4: In this example, we will see the use of the _.neq() method.
javascript
// Defining underscore contrib variable const _ = require( 'underscore-contrib' ); let neq = _.neq(2, 2, 2); console.log( "Each arguments are not equal to previous one :" , neq); |
Output:
Each arguments are not equal to previous one : false
