Lodash _.isIncreasing() 方法
Lodash _.isIncreasing() 方法检查给定值是否单调递增(每个参数都大于前一个参数)。
句法:
_.isIncreasing(val1, val2, ..., valn);
参数:此方法需要 n 个值来检查递增顺序。
返回值:此方法返回一个布尔值(如果给定值增加则返回真,否则返回假)。
注意:这在普通 JavaScript 中不起作用,因为它需要安装 lodash.js contrib 库。 Lodash.js contrib 库可以使用npm install lodash-contrib 安装。
示例 1:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Check for increasing order
console.log("The Value is Increasing order : "
+ _.isIncreasing(1, 2, 3, 4));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Check for increasing order
console.log("The Value is Increasing : "
+ _.isIncreasing(3, 2, 1, 2));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Check for increasing order
console.log("The Value is Increasing : "
+ _.isIncreasing('a', 'b'));
console.log("The Value is Increasing : "
+ _.isIncreasing('c', 'b', 'a'));
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Check for increasing order
console.log("The Value is Increasing : "
+ _.isIncreasing("Geeks", "GFG"));
console.log("The Value is Increasing : "
+ _.isIncreasing('g', 'G'));
输出:
The Value is Increasing order : true
示例 2:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Check for increasing order
console.log("The Value is Increasing : "
+ _.isIncreasing(3, 2, 1, 2));
输出:
The Value is Increasing : false
示例 3:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Check for increasing order
console.log("The Value is Increasing : "
+ _.isIncreasing('a', 'b'));
console.log("The Value is Increasing : "
+ _.isIncreasing('c', 'b', 'a'));
输出:
The Value is Increasing : true
The Value is Increasing : false
示例 4:
Javascript
// Defining lodash contrib variable
