Underscore.js _.lte() 方法
这 _。 lte()方法检查每个参数是否小于或等于其下一个参数。
句法:
_.lte( 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。

// Defining underscore contrib variable
var _ = require('underscore-contrib');

输出:
Each argument is lesser than or equal to its next argument : true
示例 2:
// Defining underscore contrib variable
