Lodash _.neq() Method

  • Last Updated : 29 Sep, 2020

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.neq() method checks whether each argument is not equal to the previous argument, using loose inequality (!=) and returning a boolean correspondingly.

Syntax:

_.neq( val1, val2, ..., valn )

Parameters: This method takes a variable number of values to operate on them.

Return Value: This method returns a boolean value.



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

Example 1:

Javascript




// Defining lodash contrib variable 
var _ = require('lodash-contrib'); 
  
// Using the _.neq() method
var 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:

Javascript




// Defining lodash contrib variable 
var _ = require('lodash-contrib'); 
  
// Using the _.neq() method
var neq = _.neq( 8, 8 );
  
console.log(
  "Each arguments are not equal " +
  "to previous one :", neq
);

Output:

Each arguments are not equal to previous one : false

Example 3:

Javascript




// Defining lodash contrib variable 
var _ = require('lodash-contrib'); 
  
// Using the _.neq() method
var neq = _.neq( 8, 6, 4, 12 ); 
  
console.log(
  "Each arguments are not equal " +
  "to previous one :", neq
);

Output:

Each arguments are not equal to previous one : true

Example 4:

Javascript




// Defining lodash contrib variable 
var _ = require('lodash-contrib'); 
  
// Using the _.neq() method
var neq = _.neq( 8, 8, 8, 8 );
  
console.log(
  "Each arguments are not equal " +
  "to previous one :", neq
);

Output:

Each arguments are not equal to previous one : false
