Lodash _.isIncreasing()用法及代码示例


Lodash _.isIncreasing()方法检查给定的值是否单调增加(每个参数都大于前一个参数)。

用法:

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

参数:此方法采用n个值检查递增顺序。

返回值:此方法返回一个布尔值(如果给定值增加,则返回true,否则返回false)。

注意:由于它需要安装lodash.js contrib库,因此在常规JavaScript中将无法使用。可以使用npm install lodash-contrib来安装Lodash.js contrib库。

// Defining lodash contrib variable  
var _ = require('lodash-contrib');  
  
// Check for increasing order

输出:

The Value is Increasing order:true
