Underscore.js _.lt() 方法

_.lt()方法检查每个参数是否小于其下一个参数。

句法:

_.lt( val1, val2, ..., valn );

参数:此方法需要 n 个值对其进行操作。

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 underscore.js contrib 库。

underscore.js contrib 库可以使用npm install underscore-contrib –save 安装。

示例 1:

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
var lesser  = _.lt(1, 4);
console.log("Each argument is lesser than its next argument :", lesser);

输出:

Each argument is lesser than its next argument : true

示例 2:

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
var lesser  = _.lt(1, 4, 9);
console.log("Each argument is lesser than its next argument :", lesser);

输出:

Each argument is lesser than its next argument : true

示例 3:

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
var lesser  = _.lt(1, 4, 4);
console.log("Each argument is lesser than its next argument :", lesser);

输出:

Each argument is lesser than its next argument : false
