Lodash _.neq() 方法

Lodash是一个基于 underscore.js 的 JavaScript 库。 Lodash 有助于处理数组、字符串、对象、数字等。

_.neq() 方法检查每个参数是否不等于前一个参数,使用松散不等式 (!=) 并相应地返回一个布尔值。

句法:

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

参数:此方法采用可变数量的值对它们进行操作。

返回值:此方法返回一个布尔值。

注意:这在普通 JavaScript 中不起作用,因为它需要安装 lodash contrib 库。 Lodash contrib 库可以使用npm install lodash-contrib –save 安装

示例 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
);


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
);


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
);


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
);


输出:

Each arguments are not equal to previous one : true

示例 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
);

输出:

Each arguments are not equal to previous one : false

示例 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
);

输出:

Each arguments are not equal to previous one : true

示例 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
);

输出:

Each arguments are not equal to previous one : false
