zyh-array

一些数组方法 zouSort,zouQuery

zouQuery 数组及数组对象查询方法

数组查询 zouQuery(arr,query)

---

两个参数数组和要查找的元素,返回值是查找的元素和元素所在的索引,失败返回查找失败

 const zyh=require('zyh-array') 
let arr1=[1,5,8,8,9]
let obj = zyh.zouQuery(arr1,5)
console.log(obj); //返回5索引值1

数组对象查询 zouQuery(arr,query,true)

---

1. 参数1 数组对象 arr
2. 参数2 查询元素(可以是任意类型)与数组对象中的元素进行匹配 , 只要是数组对象中有的值有查询元素,就会以数组方式返回当前对象
3. 参数3 加true代表开启数组对象查询

    }] 

const zyh=require('zyh-array')
const data =require('./singers.json')   
const arr=data.singers

let obj1 = zyh.zouQuery(arr,5,true)
let obj2 = zyh.zouQuery(arr,"林俊杰",true)

console.log(obj1)
[
      "陈奕迅",

zouSort 数组基本方法

1. 参数
2. 参数1:数组
3. 参数2:数字(1,2,3,4)
4. zouSort=(数组,数字)
5. 数字1为:冒泡排序
6. 数字2为:数组去重
7. 数字3为:求最大值
8. 数字4为:求最小值

const s = require('zyh-array')

let arr=[1,55,55,66,44]

s.zouSort(arr,1)//1,44,55,55,66

s.zouSort(arr,2)//1,44,55,66

s.zouSort(arr,3)//66

s.zouSort(arr,4)//1
